The efficiency and reliability of pumps are highly related to their operation conditions. The concept of the optimization pump operation conditions is to adjust the operation point of the pump to obtain higher reliability at the cost of lower system efficiency using a joint regulation of valve and frequency convertor. This paper realizes the control of the fluid conveying system based on the optimization results. The system is a nonlinear Multi-Input Multioutput (MIMO) system with time delays. In this paper, the time delays are separated from the system. The delay-free system is linearized using input-output linearization and controlled using a sliding mode method. A modified Smith predictor is used to compensate time delays of the system. The control strategy is validated to be effective on the test bench. The comparison of energy consumption and operation point deviation between conventional speed regulation and the new method is presented.

PID control systems are the most commonly used control technology in industries. However, there are issues on control performances for the unstable process with time delays. In order to improve the control performances of PID control systems, a new two degree of freedom model driven PID control system is introduced in this paper and it is used to the unstable processes with time delay. The model driven PID control is capable of stabilizing with unstable processes by using PD feedback, regulating quickly for disturbance and tracking quickly to the change of set point. With case studies comparing with conventional PID control systems was done.

I’m especially pleased to send you my congratulations on the publication of “International Journal of Automation Technology”. The automation technology has the extremely clear purpose of replacing human work with automated system. However, the automation technology requires various kinds of technologies, ranging from mechanical technology, electronics, control technology, software technology for computer, to system technology necessary for those to be functioned effectively. Therefore, people, who start to learn the automation technology or keep up on it, cannot help gathering fragmentary information from many kinds of technology fields. Additionally, relationship and collaboration between academic institute and industries are important issues that mean industrial firms investigate mostly practical applications of automated machines and production systems, while mainly universities and institutes research fundamental and elemental technologies. With these backgrounds, it has been tough to grasp its whole picture of the automation technology in general, although some of leading universities, institutes and industry firms themselves advance and accumulate the automation technology systematically. This time, through publishing “International Journal of Automation Technology”, I believe the automation technology must become popular and familiar for a great number of engineers, researchers and students. Especially, this publication is delightful news for young engineers, who work toward advanced automation in global business. I greatly expect this journal play a roll of network among engineers and researchers working on the automation in various technology fields, to help upskilling and stimulation for them, and to contribute the development of the automation technology itself as well.

Fluid mechanical simulation is a typical high-performance computing problem. Due to the development of high-precision parallel algorithms, traditional computing platforms are unable to satisfy the computing requirements of large-scale algorithms. The Sunway TaihuLight supercomputer, which uses the SW26010 processor as its computing node, provides a powerful computing performance for this purpose. In this paper, the Sunway hierarchical parallel fluid machinery (swHPFM) framework and algorithm are proposed. Using the proposed framework and algorithm, engineers can exploit the parallelism of the existing fluid mechanical algorithm and achieve a satisfactory performance on the Sunway TaihuLight. In the framework, a suitable mapping of the model and the system architecture is developed, and the computing power of the SW26010 processor is fully utilized via the scratch pad memory (SPM) access strategy and serpentine register communication. In addition, the framework is implemented and tested by the axial compressor rotor simulation algorithm on a real-world dataset with Sunway many-core processors. The results demonstrate that we can achieve a speedup of up to 8.2×, compared to the original ported version, which only uses management processing elements (MPEs), as well as a 1.3× speedup compared to an Intel Xeon E5 processor. The proposed framework is useful for the optimization of fluid mechanical algorithm programs on computing platforms with a heterogeneous many-core architecture.

scqubits is an open-source Python package for simulating and analyzing superconducting circuits. It provides convenient routines to obtain energy spectra of common superconducting qubits, such as the transmon, fluxonium, flux, cos(2ϕ) and the 0-π qubit. scqubits also features a number of options for visualizing the computed spectral data, including plots of energy levels as a function of external parameters, display of matrix elements of various operators as well as means to easily plot qubit wavefunctions. Many of these tools are not limited to single qubits, but extend to composite Hilbert spaces consisting of coupled superconducting qubits and harmonic (or weakly anharmonic) modes. The library provides an extensive suite of methods for estimating qubit coherence times due to a variety of commonly considered noise channels. While all functionality of scqubits can be accessed programatically, the package also implements GUI-like widgets that, with a few clicks can help users both create relevant Python objects, as well as explore their properties through various plots. When applicable, the library harnesses the computing power of multiple cores via multiprocessing. scqubits further exposes a direct interface to the Quantum Toolbox in Python (QuTiP) package, allowing the user to efficiently leverage QuTiP's proven capabilities for simulating time evolution.

Technology improves performance and reduces in size day by day. Reduction in size can increase the density and which in turn can improve the performance. These statements suit very well for the computer architecture improvement. The whole System on Chip (SoC) brought the concept of multiple cores on a single chip. The multi-core or many-core architectures are the future of computing. Technology has improved in reducing the size and increasing the density, but improving the performance to an expectation of including more cores is a challenge of many-core technology. Utilization of all cores and improving the performance of execution by these cores are the challenges to be addressed in a many-core technology. This paper discusses the basics of many core architecture, comparison and applications. Further, it covers the basics of Network on Chip (NoC), architectural components, and various views of current Network on Chip research problems. Research problems include improving the performance of communication by avoiding congested path in routing.

Abstract Over the past years, with the development of hardware and software, the intelligent sensors, which are deployed in the wearable devices, smart phones, and etc., are leveraged to collect the data around us. The data collected by the sensors is analyzed, and the corresponding measures will be implemented. However, due to the limited computing resources of the sensors, the overload resource usage may occur. In order to satisfy the requirements for strong computing power, edge computing, which emerges as a novel paradigm, provides computing resources at the edge of networks. In edge computing, the computing tasks could be offloaded from the sensors to the other sensors for processing. Despite the advantages of edge computing, during the offloading process of computing tasks between sensors, private data, including identity information and address, may be leaked, which threatens personal security. Hence, it is important to avoid privacy leakage in edge computing. In addition, the time consumption of offloading computing tasks affects the using experience of customers, and low time consumption makes contributions to the development of applications which are strict with time. To satisfy the above requirements, a time-efficient offloading method (TEO) with privacy preservation for intelligent sensors in edge computing is proposed. Technically, the time consumption and the offloading of privacy data are analyzed in a formalized way. Then, an improved of Strength Pareto Evolutionary Algorithm (SPEA2) is leveraged to optimize the average time consumption and average privacy entropy jointly. At last, abundant experimental evaluations are conducted to verify efficiency and reliability of our method.
