Abstract :
Based on analyzing the structure characteristics of a multivariable grey model, a novel design method of grey prediction PID control is proposed according to the control requirements of a discrete system. Combining the grey system theory with digital PID control, a grey model GM (0, N) of the discrete system is constructed and in the initial stage the control effect is directly determined by a digital PID controller. Meanwhile, the parameters of the GM (0, N) model are estimated via generating operation. Then the compensation controller is employed to eliminate the influence of uncertain parts on system performance by utilizing the prediction control variable due to parameter estimation. Finally, a simulation experiment for the control system is taken on Matlab. Simulation results demonstrate the effectiveness and the practicability of this control method for a discrete system.
