Automatic Control System for Power Supply Frequency of Coal Mine Electrical Equipment Based on Fuzzy Single Neuron PI
To ensure that the power frequency of coal mine electrical equipment does not deviate from the standard frequency and ensure the safe and stable operation of coal mine electrical equipment,an automatic control system for power frequency of coal mine electrical equipment based on fuzzy single neuron PI is designed.The data acquisition layer outputs the power frequency signal to the detector,collects power frequency data,and uses the improved wavelet threshold method to denoise the frequency data.Then,the data transmission layer sends it to the control center.The control center receives the data while using the ideal power frequency solution module to predict the ideal power fre-quency through a multiple regression model.Then,the fuzzy neural PI control module takes the actual and ideal power frequency as inputs,The control signal is obtained by solving the frequency deviation and fuzzing,and the pow-er frequency is controlled to approach the ideal value wirelessly.The experimental results show that the system can achieve automatic control of the power frequency of coal mine electrical equipment,and control the power frequency of the equipment to approach the ideal value wirelessly,the power frequency control effect is significant.
