| Abstract: | An approach of direct synthesis of proportional,integral,and derivative controller（PID） for unstable time delayed process was presented.The design procedure includes tuning the parameters of idea PID controller for process with constraints of special time domain indexes,and moving the derivative law to inner loop so that no derivative operation is on set-point signal,and combining whole three elements into the set-point weighted PID controller.Simulation results show that the proposed approach is an effective method and its control systems have proper robust stability. |
