Pressure and vacuum servo control system based on vacuum pump and study of the system control

A novel pressure and vacuum servo control system using a vacuum pump is presented in the paper. The system combines vacuum technology and pneumatics servo control technology. By applying different controllers (PID controller, intelligent gene fuzzy controller and Fuzzy-PID controller) to the system, the simulation and experimental results show that it is practicable and reasonable to adopt the fuzzy-PID control strategy in the pressure and vacuum servo control system based on vacuum pump. The servo control system behaves stronger robustness, better adaptive ability, higher steady control accuracy and faster response. The study also show that the pressure and vacuum servo control system based on vacuum pump is feasible and can greatly realize the servo control of the vacuum signal with high accuracy and fast response.
