摘要
通过非线性系统的部分线性化方法，将两类各自满足相应条件的不确定非线性系统的最优控制问题分别变换成参数确定和参数不确定线性系统的二次型最优调节器问题，从而求得原最优控制问题的闭环解析解。两个设计例子及其仿真结果验证了本文方法的正确性。
Optimal control problems of two classes of uncertain nonlinear systems are studied by partial linearization method. The problems are transformed into certain parameter and uncertain parameter linear quadratic regulator problems respectively. The closed loop analytic solutions of the original optimal control problems are provided. The correctness of the design methods of this paper is verified by two examples and their simulation results.
