Neural network does not depend on the model of the control object. It can approach the dynamic behavior of the unknown non-linear object by learning, so it can be used in the control of three-level PWM rectifier. However, due to the requirement of fast and real-time performance of three-level PWM rectifier, the practical application of

In the production process of modern pig farm, it is necessary to detect the harmful gases that affect the health of pigs in the pig house, so as to facilitate the pig farm to make production decisions. A wireless detection and acquisition system for harmful gases in piggery based on STM32 is designed. The whole

This paper introduces the design principles and steps of the programmable controller system, and explains the problems that should be considered in the design of the system. The principle of the design of PLC control system is to make up the electrical control system with PLC as the core to realize the automatic control of

Programmable Controller (hereinafter referred to as PLC) technology is a widely used and practical course in the field of industrial control. In view of the abstract characteristics of the course content and the existing problems in the teaching of secondary vocational schools, this paper takes the information-based teaching design of the teaching unit of “Automatic

Comfort, safety and diversity have become the development trend of automobile industry. Body control module is the core of body function requirements. In this paper, the overall scheme of body control based on CAN/LIN bus is designed, which is mainly CAN bus and assisted by LIN bus. The hardware of the front body controller is

With the tide of industrial automation and intellectualization coming, people’s life style has changed dramatically. People’s medical environment and medical equipment have further realized intellectualization. This paper mainly uses STM32 microcontroller to control the dispensing device of automatic dispensing machine through CAN bus. The dispensing device of traditional dispensing machine is mainly connected. Through PLC

At present, the main content of LED street lamp is illuminating through street lamp, and the control of street lamp is scarce. Although the field of intelligent control develops rapidly at this stage, it is difficult to automatically detect the illumination of street lamp, so there is still a long way to go in the

In order to solve the problem of data storage in radar digital beamforming system, a FLASH controller based on FPGA is designed in this paper. The read-write control of FLASH is realized by finite state machine, and the design is verified by simulation in modelsim. The correctness and reliability of the design are proved by

Active disturbance rejection controller (ADRC) has poor control performance under strong disturbance system and large time delay. The main influence factor is the static parameter mechanism. Therefore, an ADRC based on joint optimization of differential evolution algorithm and particle swarm optimization (PSO) is designed. The particle swarm optimization (PSO) algorithm is used to optimize the

This paper expounds the characteristics and principles of driver controller of type 3 EMU, points out its structural defects, and puts forward optimization suggestions. Driver controller is the main control device used by drivers to control locomotive operation. It can realize locomotive traction, braking, speed regulation, commutation and other functions. It is frequently used in
