针对水压控制系统中存在的滞后和扰动,采用一种基于GM(1,1)模型的灰色预测PID控制算法,所设计控制器的主要优点是不需要建立水压控制系统的数学模型,以系统行为代替系统的数学模型,可预测水压的变化,提前补偿,提高了系统的稳定性和控制精度。仿真及对比试验表明,所采用的算法是有效的。 Aiming at the hysteresis and disturbance existing in the hydraulic control system, a gray prediction PID control algorithm based on the GM (1,1) model is adopted. The main advantage of the designed controller is that it does not need to establish the mathematical model of the hydraulic control system System behavior instead of the mathematical model of the system can predict changes in water pressure, early compensation, improve system stability and control accuracy. Simulation and comparison tests show that the algorithm used is effective.
