加权多步预报控制
Weighted Long-Range Predictive Control
-
摘要: 本文提出了一类加权多步预报控制(WLPC)算法.这种算法是由极小化一个很一般的 加权二次型性能指标得到的.由于权因子可以根据闭环极点配置、前馈零点增补和动态性能 要求任意选取,所以可保证闭环系统的稳定性和对建模误差的鲁棒性.文中给出了这方面结 果的理论证明和仿真实例.Abstract: A new type of generalized algorithm for weighted long-range predictive control (WLPC) is proposed in this paper. The algorithm is formed by minimizing a cost function which contains some weighting factors. As these weighting factors can be chosen flexibly, the closed-loop poles can be set arbitrarily. The closed-loop stability and robustness against structured and unstructured uncertainties can be assured.
