In the article a method to carry out a synthesis of regulators of the drying plant control system is considered based on the integration of known statistical data by the Lagrange polynomial. An algorithm to correct the parameters of regulators in problematic modes of operation of the drying plant is proposed. It is shown that the control system developed and implemented on the PLC provides stable control of temperature and humidity during the drying of materials

This study aims to interpret in depth the cultural values ​​of Confucianism reflected in the management control system of Chinese ethnic families in Minangkabau. This study uses qualitative interpretive. The process of this research is interactive and meaning that is not measured by statistical data and aims to explore various information more in depth and makes it possible to get things implied by data collection carried out in triangulation. Data analysis is inductive and the results of qualitative research emphasize the meaning of generalization. This interpretive research method seeks to formulate a question and then analyze it based on the question of participants' perceptions studied. This research was conducted in one of the food trading businesses in the city of Padang, namely UD. KBF. The results of the study can be concluded by interpreting Confucian cultural values ​​in the implementation of the management system of Chinese ethnic family companies. This study found that Confucian values ​​were reflected in the implementation of the company's management control system UD. KBF. The values ​​applied by the company's leadership are

We obtained the condition absolute stability on the derivative for the control system of electromagnetoelastic actuator for communication equipment. We applied the frequency methods for Lyapunov stable control system to calculate the condition absolute stability control system of electromagnetoelastic actuator. We used Yakubovich criterion absolute stability system with the condition on the derivative. The aim of this work is to determine the condition of the absolute stability on the derivative for the control system of electromagnetoelastic actuator. We received the stationary set of the control system of the hysteresis deformation of the electromagnetoelastic actuator. The stationary set is the segment of the straight line.

Stable Control

Although the Takagi–Sugeno fuzzy model is effective for representing the dynamics of a plant to be controlled, two main questions arise when using it just as other models: 1) how to deal with the gap, which is referred to as uncertainty in this study, between the model and the concerned plant, and how to estimate the state information when it cannot be obtained directly, especially with the existence of uncertainty; 2) how to design a controller that guarantees a stable control system where only the estimated state is available and an uncertainty exists. While the existing studies cannot effectively observe the state and the resulting control systems can only be managed to be uniformly stable, this study first presents a state observer capable of precisely estimating the state regardless of the existence of uncertainty. Then, based on the state observer, an uncertainty observer is derived, which can track the trajectory of uncertainty whenever it occurs in a real system. Finally, a controller based on both observers is presented, which guarantees the asymptotic stability of the resulting control system.

Arduino Microcontroller

In this Digital era, Microcontrollers are now growing rapidly and are increasingly in demand in control system applications. Including Arduino Microcontroller, by using this Arduino trying to overcome a problem that often occurs in the Data Center space, namely the problem of temperature and humidity instability that has a major impact on data on each rack in the data center space. This problem occurs if the temperature is too hot or too excessive humidity which results in overheating so that it can damage data stored in the data center. To solve the problem, Arduino detects temperature and humidity using a DHT11 module that can detect clearly and accurately, and can display on the LCD screen, or display the results of temperature and humidity detection on a webbased Thingspeak application and the Blynk application that can be accessed via a smartphone. Internet-based of Things (IoT). With DHT11 processed by Arduino can produce an ideal temperature of 18 ° C - 28 ° C and humidity of 40.00% - 60.00%, and provide Notifications that will be sent to the blynk application if there are problems with temperature and humidity instability.

PurposeDespite of the numerous characteristics of the multirotor unmanned aircraft systems (UASs), they have been termed as less energy-efficient compared to fixed-wing and helicopter counterparts. The purpose of this paper is to explore a more efficient multirotor configuration and to provide the robust and stable control system for it.Design/methodology/approachA heterogeneous multirotor configuration is explored in this paper, which employs a large rotor at the centre to provide majority of lift and three small tilted booms rotors to provide the control. Design provides the combined characteristics of both quadcopters and helicopters in a single UAS configuration, providing endurance of helicopters keeping the manoeuvrability, simplicity and control of quadcopters. In this paper, rotational as well as translational dynamics of the multirotor are explored. Cascade control system is designed to provide an effective solution to control the attitude, altitude and position of the rotorcraft.FindingsOne of the challenging tasks towards successful flight of such a configuration is to design a stable and robust control system as it is an underactuated system possessing complex non-linearities and coupled dynamics. Cascaded proportional integral (PI) control approach has provided an efficient solution with stable control performance. A novel motor control loop is implemented to ensure enhanced disturbance rejection, which is also validated through Dryden turbulence model and 1-cosine gust model.Originality/valueRobustness and stability of the proposed control structure for such a dynamically complex UAS configuration is demonstrated with stable attitude and position performance, reference tracking and enhanced disturbance rejection.
