Aircraft power supply system plays an important role in aircraft system. Generator controller (GCU) for monitoring power supply system is an important device to ensure the safe operation of power supply system. 　　In order to ensure the normal operation of generators and the safe flight of aircraft, it is necessary to regularly test and maintain

In order to improve the teaching quality of Programmable Controller course in Higher Vocational colleges, teachers should first change their teaching ideas. Interest is the best teacher for students and employment is the guiding principle for Higher Vocational education. Therefore, in the process of teaching, more attention should be paid to enhancing students’learning interest and

Common washing machine controller has single function, easy to damage and inaccurate timing. With the development of modern science and technology and the improvement of management level, ordinary washing machines can not meet people’s requirements. This design is to use the principle of fuzzy control to automate the transformation of the ordinary washing machine controller,

According to the requirement of grid-connected, the magnitude and phase of the output voltage at the end of the line must be consistent with the magnitude and phase of the large grid voltage in the process of grid-connected photovoltaic microgrid. When the output voltage of photovoltaic micro-grid does not meet the grid-connected conditions, UPFC can

In order to solve the drawbacks of low calibration efficiency and low test accuracy of manual debugging parameters in the original PLC production process, a small PLC automatic controller is designed and implemented. The functions of AIO module, DIO module, PTA module and CPU module in PLC hardware are analyzed in detail. Based on the

The body controller is the core component of the automobile to realize the interaction function with the user. The reliability of its function is directly related to the user’s experience effect and safety factors. In the design and verification stage of the body controller, the reliability of DV experiment must have strict requirements, and the

Micro-logic controller not only can be programmed and controlled, but also covers some functions of traditional relay. From the application level, Micro-Logic controller fills the gap between traditional relay and PLC. Taking the electric control of electric hoist as an example, this paper introduces the simplicity and intelligence of microcontroller in comparison with traditional relay

This paper presents a constant temperature and humidity controller based on Internet of Things cloud service platform. 　　The hardware design of the controller is introduced in detail from the aspects of processor, Ethernet module, temperature and humidity sensor and I2C interface, relay module and current output module. The actual results show that the controller has

Due to the design flaws, the controller of distribution automation demarcation switch is often operated or adjusted by non-distribution secondary operators in operation, resulting in widening the scope of power failure and accident. Therefore, Zibo Power Supply Company developed a locking device for user demarcation switch, and achieved good results in application. With the development

In the grinding process, a large number of PID controllers are needed. In this paper, the improved algorithm of global optimization is studied in depth, and combined with the PID controller, the global optimization PID controller is formed. The simulation results of MATLAB show that the intelligent PID controller has good effect and strong stability.
