Research on Servo Press Controller Based on Fractional Order Control Algorithm

In order to solve the problems of servo press control system precision about large inertia and low precision, the controlling theory of fractional order (PID mu)-D-lambda and the digital realization of fractional order controller had been proposed, which based on the slide motion characteristics. The design flexibility, the system stability and controlling effect of traditional integer order PID controller can be improved with the application of the fractional order calculus of fractional order controller. The press position servo system model was established in Matlab/Simulink to verify the controlling effect of fractional order controllers. The simulation results show that the controlling effect of fractional order (PID mu)-D-lambda controller was better than traditional integer order PID controller.
