摘要
本文给出了广义顶测控制(GPC)的稳定性的理论证明,并对其鲁棒性和其他性能进行了比较完整的理论分析,得出了以下主要结论:(1)降阶建模时,GPC对建模误差的鲁棒性不够好;(2)GPC对噪声较敏感;(3)不存在结构型建模误差且噪声强度不大时,自校正GPC是一性能良好且适用面广的控制算法。理论分析及仿真结果都表明,GPC并没有解决自适应控制的基本问题——鲁棒性问题。
This paper gives a theoretical proof about the stability of Generalized Predictive Control(GPC)and a more complete analysis of its robustness and other performances. Three results have been gotten:(1)GPC has poor robustness against the modeling errors when reduced order modeling.(2)GPC is more sensitive to the random disturbances.(3)GPC is a good control algorithm with a extensive use-range when the unstructured uncertainties do not exist and the strength of the random disturbance is not great. Both the theoretical anaysis and the simulation show that GPC is failed to solve the basic problem of adaptive control-robustness.
