A modified generalized predictive（GPC） PID control algorithm is studied to solve the problem oriented to complex large time delay controlled object.On the premise of the assurance of classic PID control performance,the optimization of the receding horizon principle is used to self-tune PID control parameters,while addressing the control problems caused by system time delay.The final results of the simulation analysis show that using Toeplitz equation algorithm can effectively improve the system stability and fast calculation.
