The Transformation of Traditional Air Compressor Based on Fuzzy-PID Control Strategy

The method of using loaded and unloaded air supply control on the traditional air compressor not only makes the supply pressure unstable, but also makes frequently changing of the load state of the air compressor and causes economic losses. In order to save energy and improve efficiency,it designs a self-tuning PID control system based on parameter fuzzy to complete the transformation of the traditional air compressor.It uses C8051F020 microcontroller to control the closed-loop PWM frequency control system.After the transformation, the system can adjust the motor speed according to the size of gas consumption, and realize precisely constant gas pressure supply.It can be used in machinery,chemical industry and many other fields.
