失配不确定性系统的局部调节器设计

提出了局部调节等概念，研究了一种新的调节器──局部调节器，在各种失配不确定性因素的作用下保证其输出等关键状态变量稳态无误差地收敛于零。最后给出算例验证了所得结论。

A Partial Regulator Design Effective Despite Mismatched Uncertainties

In practical plants, mismatched uncertainties widely exist and usual1y cause large steady - state convergence errors that are unacceptable. To our best knowledge, this problem has not been solved.For solving this problem, We propose two new concepts: (1) partial regulator, (2) regulation degree. We propose a specinc control system structure for partial regulator (Fig. 1).It is proved that the partiai regulator ensures zero steady -state convergence errors for several key state variab1es of a control system such as outputs even under the action of mismatched uneertainties. Furthermore, a theorm is given, stating that the maximum regulation degree is the ratio of the control vector dimension to state variable dimension of a system. Finally, results of a simu1ation example (Fig. 2) confirm preliminarily the above conclusions.
