This paper introduces the teaching reform of “Principles and Applications of Programmable Controller” from three aspects of teaching reform: syllabus, experimental syllabus and assessment methods, diversified teaching methods, strengthening practical teaching reform, encouraging schools to participate in various competitions, and strengthening the construction of teaching staff. Leather and Practice. With the rapid development of industrial

A hardware-in-the-loop testing system (HIL) for automatic testing of vehicle air-conditioning controller is proposed. 　　The design scheme of HIL software and hardware is introduced comprehensively. 　　The automatic testing of logic function of vehicle air-conditioning controller is completed by building test model, editing and executing test program. With the development of automobile intellectualization, networking and ecology,

Colorful lights play an important role in beautifying and brightening the city. As an important part of the color lamp, the color lamp controller has attracted much attention. The traditional color lamp control circuit is generally composed of digital circuits, so the structure is complex, the cost is high and the power loss is large.

The output characteristics of photovoltaic cells are studied and the maximum power is tracked. The voltage and current from the maximum power point are charged to the battery. The DC-DC power converter is designed to isolate the photovoltaic array from the battery. The controller charges and protects the battery. The matlab simulation shows the charging

An electric vehicle air conditioning controller based on single chip computer is studied. It has the advantages of low cost, accurate temperature control, simple, convenient, energy-saving and pollution-free, and has good application and development prospects. It is an inevitable trend for the development of automobile industry that new energy vehicles gradually replace traditional petroleum energy

Microsoft’s Windows Hybrid Reality Head Display Device has begun to be shipped to developers, but for users, the system is incomplete only with Head Display and no motion control handle. Although this control is not the most beautiful in design, it has an impressive function, that is, as a full-featured controller, it does not need

The unbalanced vibration of the rotor will seriously affect the stability and safety of the magnetic suspension switched reluctance motor (BSRM) in operation. On the basis of introducing the principle of generating the suspension force of the BSRM rotor, the dynamic equation of the rotor is derived. The decoupling control model of BSRM suspension force

Aiming at the shortcomings of the existing design scheme of brushless DC motor controller, a design scheme of brushless DC motor controller based on FPGA platform is proposed. The speed and current double closed-loop control system of motor is designed by using FPGA. The hardware of the system includes the control circuit with the core

In the avionics system, the application and demand of discrete digital circuits are increasing, while the traditional discrete interface chips have low integration and high power consumption, and it is difficult to guarantee the stability and reliability of discrete quantities in harsh environments. Based on the above limitations, this paper introduces a new discrete digital

Hybrid electric vehicle (HEV) can organically combine engine, motor, power battery and other components. 　　 　　It can give full play to the advantages of internal combustion engine vehicle and electric vehicle. It is an important method to reduce oil consumption and carbon dioxide emissions. In the development of hybrid electric vehicle, vehicle controller is the
