ADRC has the advantages of small overshoot, thermostatic element fast response and strong anti-disturbance ability. However, up to now, there is still no unified and effective theory to support parameter tuning. In this paper, based on genetic algorithm, the parameter tuning is transformed into a multi-constrained nonlinear programming problem and solved. Finally, based on a

CKY40 Programmable Logic Controller (PLC), as an important part of air conditioning unit of railway passenger car, intellectualizes the control of air conditioning device of railway passenger car. In the process of practical operation of railway passenger car, PLC failures occur from time to time, which affects the performance of air conditioning device of railway

As the core of SDN network, the robustness of SDN controller is one of the key factors affecting SDN network. The change of switch connection state caused by the unreliability of management channel in SDN network is the main reason that affects the stability of SDN controller. In this paper, by introducing a new state

With the gradual improvement of people’s awareness of power supply safety, dual power supply circuit must be used in many occasions to ensure safe and reliable power supply. In this paper, the double power automatic switching system based on PLC uses undervoltage relay to detect, which ensures the safety and reliability of the circuit and

In this paper, the 16-bit dsPIC33EP series chip controller of Microchip Company is used as the main digital chip of switching power supply. The design scheme of digital control multi-output is introduced. The corresponding hardware and software design are carried out and the principle prototype is made.The experimental verification of the prototype shows that the

With the arrival of the era of “machine replacement” and “industry 4.0”, industrial automation system has been basically realized in enterprises nowadays. Programmable Logic Controller (PLC) is the most commonly used control device in industrial automation system. It has been widely used in steel, printing and dyeing, chemical industry, paper making and mechanical processing and

In recent years, with the rapid development of science and technology, the application of single-chip computer is constantly going deep, while driving the traditional control and detection to update with each passing day. In the application system of real-time detection and automatic control, single-chip computer is often used as a core component. The knowledge of

Based on the understanding of the current heating situation in rural areas, a controller of biomass fuel heating furnace is designed by using STM32F103C8T6 chip to solve a series of problems in winter heating in rural areas. According to the information of room temperature and water temperature detected by K-type thermocouple, the combustion speed of

At present, the model of hardware integrated controller used by Jilin Meteorological Bureau is DPZC-1. The hardware integrated controller consists of software (communication control software driver and SMOPORT software), hardware (communication control module, photoelectric conversion cat, optical fiber, network equipment). This paper mainly introduces the composition and working principle of the hardware integrated controller, and

According to the road vehicle function safety standard ISO26262, the concept stage design of the whole vehicle controller of pure electric vehicle is carried out. Firstly, the activities in the conceptual stage of the third chapter of ISO262 standard are analyzed. On this basis, the object definition of vehicle controller VCU is completed. Hazard analysis
