Programmable Controller (PLC) is an industrial control device with rapid development and wide application in recent years. With the continuous development of PLC technology, in the field of automation design, the application scope of PLC technology is gradually expanding. 　　PLC has gone through more than 40 years of development and has been widely used all

Aiming at the problem of non-linear modeling of electro-hydraulic position servo system of valve-controlled cylinder, a neural network is used to identify the system model. LM genetic algorithm is used to modify the weights and thresholds of the three-layer BP neural network, and the input/output data of the training system is used to establish the

The self-tuning PID controller based on membrane computing uses the computing power of the distribution and parallelism of membrane computing to real-time tune the three parameters of the PID, so as to achieve the desired purpose. Now the self-tuning PID controller based on membrane computing is divided into two parts, the PID parameter tuning based

Aiming at the problem of statistical delay assurance in high-speed IEEE 802.11 wireless local area network (WLAN), a novel frame aggregation algorithm of proportional-integral-differential (PID) controller is proposed. By constructing an effective capacity model, the aggregation algorithm does not need to take any channel information into account. Only using the average queue level metric, it

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
