The design of a predictive controller for pressure servo system on the basic theory and properties of the model predictive control （ MPC）, through MPC and PID control simulation study, got various factors and simulation results. These factors are included electromagnetic time constant, electromagnetic induction and torque coefficient EMF etc. Through comparison, the predictive control has strong of anti-jamming capability and robustness, its steady-state accuracy and dynamic quality are significantly superior to the traditional PID control, results showed that the predictive control can adapt the request of rapid, high-precision control algorithm controlled object and provides a theoretical basis for producing faster and more sophisticated injection molding machine with higher engineering application value.
