Automated Driving Systems (ADSs) commend a substantial reduction of human-caused road accidents while simultaneously lowering emissions, mitigating congestion, decreasing energy consumption and increasing overall productivity. However, achieving higher SAE levels of driving automation and complying with ISO26262 C and D Automotive Safety Integrity Levels (ASILs) is a multi-disciplinary challenge that requires insights into safety-critical architectures, multi-modal perception and real-time control. This paper presents an assorted effort carried out in the European H2020 ECSEL project—PRYSTINE. In this paper, we (1) investigate Simplex, 1oo2d and hybrid fail-operational computing architectures, (2) devise a multi-modal perception system with fail-safety mechanisms, (3) present a passenger vehicle-based demonstrator for low-speed autonomy and (4) suggest a trust-based fusion approach validated on a heavy-duty truck.

This study focused on the classification of EEG signal. The study aims to make a classification with fast response and high-performance rate. Thus, it could be possible for real-time control applications as Brain-Computer Interface (BCI) systems. The feature vector is created by Wavelet transform and statistical calculations. It is trained and tested with a neural network. The db4 wavelet is used in the study. Pwelch, skewness, kurtosis, band power, median, standard deviation, min, max, energy, entropy are used to make the wavelet coefficients meaningful. The performance is achieved as 99.414% with the running time of 0.0209 seconds

Hardware-in-the-Loop (HIL) emulation is poised to become unsurpassed design tool for development, testing, and optimization of real-time control algorithms for grid connected power electronics converters for distributed generation, active filters and smart grid applications. It is strongly important to examine and test how grid connected converters perform under different operating conditions including grid disturbances and faults. In that sense, converter?s controller is a key component responsible for ensuring safe and high-performance operation. This paper demonstrates an example how ultra-low latency and high fidelity HIL emulator is used to easily, rapidly and exhaustively test and validate standard control strategy for grid connected power electronics converters, without need for expensive hardware prototyping and laboratory test equipment.

The diesel generator sets digital control system based on DSP is studied in this paper. The principles of voltage and speed control are analyzed. The main DSP chip is 16-bit fixed-point TMS320LF2407A. The hardware design, the former channels, the after channels and the CAN controller are accomplished in this paper. The simulation results indicate the controller has high-performance processing capabilities and it can meet the need of Generator Sets' real-time control and performance requirements.


The intelligent approaches emerge as leading techniques in providing of stable and high performance control of industrial plants with nonlinearity, model uncertainty, variables coupling and disturbances. In the present research a novel approach for the design of a nonlinear model-free fuzzy logic controller (FLC) with two inputs – the system error and the main measurable disturbance and a rule base for disturbance compensation is suggested. It is based on off-line parameter optimisation via genetic algorithms. The approach is applied for the development of a FLC for the control of the level of ammonia brine solution in a carbonisation column with compensation of the changes in the inflow pressure. The control algorithm is implemented in a general purpose industrial programmable logic controller in ”Solvay Sodi” SA – Devnya, Bulgaria. The FLC system with disturbance compensation outperforms in an increased dynamic accuracy the FLC with the system error as a single input even when linear feedforward disturbance compensation is added. The performance of all systems is assessed from the real time control and the simulations based on a derived TSK plant model.

This paper presents an embedded controller of low cost and high performance for industrial robot. The ARM microprocessor is chosen as the main controller for the processor. Based on the 7-segment cubic spline interpolation algorithm, a real-time control for the robot is implemented. This proposed trajectory method can perfectly generates speed S-curve shape for a start-stop process of the robot. In this article a programming language, G-code, is developped for the robots motion control by using the editing interface we designed specially on PC platform. With all the features for 2-4 degree of freedom robot application, the editing interface has been developed for editing and compiling G-code, which can be downloaded into the microprocessor with the custom communication protocol through communication interface. The programming method of the G-code language is easy to learn and use for the non-professional users. The paper describes the design and implementation in detail for the controller, which was validated on our designed SCARA robot, and it worked reliably.

Abstract This paper introduces a small-scale platform for Connected Autonomous Vehicle (CAV) research that outperforms currently available commercial options in several important benchmarks. The platform is built around a Radio-Control (RC) car utilizing high-performance brushless DC motors allowing the vehicle to reach a maximum speed of 70mph, expanding the possibilities for higher speed research applications. Furthermore, this platform (named after our lab, ASIMcar, for brevity in this article) is equipped with a robust sensor suite and features a state-of-the-art embedded GPU unit for onboard computation, allowing for real-time control over a wide range of challenging operations. For demonstration and comparison, lane keeping as an Advanced Driving Assistance System (ADAS) function was implemented and evaluated using the platform. The commercially available mobile robots are expensive, offer limited capabilities, are harder to modify for various research needs, are more difficult to interface with other robots (cars), and could have proprietary software/hardware features which render them less flexible and less adaptable to specific research needs. The developed ASIMcar overcomes these limitations and provides a highly flexible and cost-effective alternative for automated/autonomous and connected vehicle research and development projects. This paper provides an in-depth description for the development of this car and lists significant features which will assist other researchers to easily and rapidly duplicate them and create a similar platform for their research.
