摘 要: 基于灰色模型GM(1,2),采用两个辨识器分别辨识被控对象和闭环系统的参数,从而得到了控制器的参数,给出了一种广义预测控制的直接算法. 由于此方法将被控对象视为灰色系统,需辨识的参数较基于CARIMA或CARMA模型的广义预测控制直接算法大大减少,实时性进一步提高. 仿真结果表明,该方法是有效可行的. This paper presents a direct generalized predictive control algorithm based on Grey Model GM(1,2). Two identifiers are used to estimate the parameters of plant and close-loop system, and to get the parameters of controller in this algorithm. Because the plant is regarded as Grey System, it would be easier to identify parameter based on Grey Model than to do it based on CARIMA model. Thus, real-time property is greatly advanced. The simulation results show efficiency of the algorithm.
