【Abstract】 Due to the lag and disturbance in water pressure, a grey predictive control algorithm based on GM(1, 1) is adopted. This controller has the major advantage that it does not require a mathematic model for the water pressure control system. The replacement of the mathematic model with the behavior of the system predicts the change of water pressure and compensate in advance, thus enhancing the stability and precision of the system. Simulation and contrast examinations show that the control algorithm is effective.更多还原
