Simulation Research on the Time-Delay Property of Different-Pressure Casting's Control System

To solve time-delay of different-pressure casting's control system, Dalin algorithm and Smith prediction algorithm are separately used to design time-delay compensation controller of different-pressure casting computer control system. And with the two controller MATLAB simulation of different-pressure casting control object is carried on. The simulation results show that Dalin algorithm and Smith prediction algorithm can both solve the time-delay of different-pressure casting control system effectively, which increases system's control precision.
