Aiming at the problem of strong dependence on prior data in neural sliding mode control system, a fractional-order speed control system of permanent magnet synchronous motor based on fuzzy RBF neural network is proposed, which combines the generalization ability and self-learning ability of RBF neural network and the strong adaptability of fuzzy inference algorithm. The

With the rapid development of national economy and the gradual formation of industry chain of independent innovation in China, the demand status of electrical control in various industries is increasing day by day. In view of the current situation of electrical industry in China, there is still a great room for improvement in the search

With the improvement of people’s requirement for vehicle comfort, AMT gearbox requires higher and higher acquisition accuracy, operation speed and stability of TCU. The design chooses Freescale 32-bit MCU K60DN512 with stable overfrequency up to 180MHz as the core, collects and processes the signals of speed and throttle opening in real time, and controls the

The energy-saving controller used in traditional production process in our country has the problem of poor control effect. In the era of high modern technology, an energy-saving controller based on electrical automation control should be designed. Firstly, we should improve and optimize the whole energy-saving control power system from the use and design of hardware,

CNC machine tools are commonly used in the production process, but the high cost of CNC machine tools often restricts the progress and development of production.In order to enrich the functions of existing CNC machine tools in China, this study explores the important technical problems of low-cost transformation of CNC machine tools by using open

This design takes STC89C52RC single chip computer as the control core, adjusts the motor speed by keys, then transmits the speed control instruction to STC89C52RC single chip computer for processing, and displays the theoretical value of DC motor speed through LCD1602 display, then processes it by STC89C52RC minimum system, thermostatic element and inputs the signal

Nowadays, the single chip computer is occupying the dominant position of the intelligent control system at the speed of rapid speed. Various kinds of color lights are also accompanied by our life. The music color lamp controller is made by AT89C51 single chip computer. Because the frequency of the single chip computer is different, when

In order to study the influence of input delay on the stability of Timoshenko beam system, a new controller is designed to compensate for the influence of input delay by using Backstepping method to stabilize the Timoshenko beam system with input delay and load at the boundary, thus a stable closed-loop system is obtained. Firstly,

In view of the contradiction between the hardware conditions of the programmable controller training room and the relatively backward training assessment methods, a method of training assessment based on lottery software is proposed. Through students’feedback, the new practice assessment method has improved the credibility of the training results, improved the information level of the practice
