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

This paper introduces the localization research, development and manufacture of MPC box on the main engine of intelligent diesel engine (ME diesel engine). Some functions of imported equipment are improved, explored and innovated. Because the electrical parts of ME-type main engine are mostly imported parts, their foreign ordering costs are high, the ordering cycle is

This paper presents the design method of software and hardware for the controller system of solar water heater, which consists of water temperature and water level sensor, single chip computer, heating relay and upper water solenoid valve. Especially, the design method of water level and temperature integrated sensor is emphasized, and the control panel of

A three-closed-loop position servo controller based on SDRAM is designed. The algorithm of the three-closed-loop control is described in detail. Combining with the application of hardware circuit in practical products, the expected technical indicators are obtained, and the dynamic characteristics of the position servo system are improved. At present, the electric position servo is regarded

In electrical information specialty, “programmable controller” is a professional course with strong practicality and comprehensiveness. The teaching effect of this course will have a certain impact on the learning of other related courses, as well as on the employment and work of students after graduation. 　　Based on the analysis of the current situation of programmable
