Based on MSP430F169 single-chip computer, Hall sensor, LCM12864, IR2130 special MOSFET chip, the brushless DC motor control system is composed of electric vehicle. The MSP430 C program is written into MSP430F169 chip, and the PWM signal is generated by the built-in timer of the single chip computer to realize voltage regulation. The position signal of

In the past, PLC control and computer control have always been the two main control modes in industrial control. In the past, the process of monitoring the state of construction machinery by PLC control system is complex and time-consuming, thermostatic element which makes the working efficiency of construction machinery low and difficult to meet the

At present, there is a general contradiction between the demand for enterprise talents and the cultivation of university talents in China’s higher education, which reflects the separation of theoretical teaching and practical teaching in teaching. This paper takes Electrical Appliances and Programmable Controller as an example to discuss the application of project-driven teaching mode. This

Programmable controllers (PLCs) are widely used in various fields of industry. They need to have the characteristics of high reliability and real-time. In order to improve the real-time performance and reliability of PLC data processing, this paper designs a special processor architecture suitable for the characteristics of PLC. At present, the requirement of real-time and

The development of electric vehicles has been established as an important way to ensure energy security and transform the low-carbon economy by all countries in the world. According to Yole, a famous French consulting company, the production and sales of electric vehicles in the world will reach 20 million by 2020, and China has set

With the continuous development of science and technology in our country, intelligent technology has been applied in many equipment to control it in an orderly way, so as to improve the overall work efficiency. It is self-evident that switch cabinet is the main control device in the power system. In the development of sensing technology,

Asynchronous motor is widely used in engineering industry. When the motor starts, it will produce a larger current, which will have a greater impact on the system itself and the power grid, and cause a waste of electricity. When the motor load is less than 75% of the rated load, the efficiency is low, resulting

In this paper, we study the non-fragile controllability of stochastic systems with both state and control input delays. The main purpose is to design a state feedback controller under admissible uncertainties so that the closed-loop system is not only mean-square asymptotically stable, but also satisfies the given performance index. By using the linear matrix inequality

Traditional PID controller has the characteristics of simple arithmetic and high control precision, but it can not achieve satisfactory control effect for the system with random disturbance and delay. Fuzzy controller has the advantages of adapting to the non-linearity and time-varying of the controlled object, but the control accuracy is not high. Therefore, a fuzzy-PID

At present, the electric heating water heater sold on the market is deeply loved by the people because of its convenient installation and use. 　　However, due to the lack of standardization in the design and construction of many building power sources in China, the safety of electric water heaters in the use process is particularly
