| 摘 要： | 传统的预测控制算法虽然有着良好的性能,但是需要求解复杂的丢番图方程.因而在实际应用中,算法的计算量很大,难以满足实时性要求.文中结合灰色理论,利用GM(1,2)模型辨识多输入多输出系统的参数,提出了一种解耦灰色预测控制算法.该算法可以采用较少的数据进行建模,需要辨识的参数也较少,并且元需求解丢番图方程,所以减少了计算量.为了消除系统各通道之间的输入输出耦合,在性能指标中引入解耦因子,给出了详细的解耦推导过程.最后,对解耦灰色预测控制算法进行了设计.仿真结果表明:本文算法能够有效地消除系统耦合,进而提高多输入多输出系统的闭环跟踪性能.

| Abstract: | Conventional predictive control algorithm possesses good overall performance,but it needs to solve the complicated Diophantine equation.Thus, the algorithm cannot meet the requirements in real time control,due to the heavy computational effort.Based on the grey prediction,a grey predictive control algorithm by adopting the identification system of GM(1,2) for MIMO system is presented.Only a few data are necessary for establishing the model, the number of the parameter to be identified is small,and it is not... |
