研究了具有结构不确定性的非线性系统的逆最优控制问题。基于控制李雅普诺夫函数，给出了系统全局渐近稳定性定理。由此导出了逆最优控制的保守性较弱的条件。利用所得结果设计了一类非线性系统的逆最优控制器，改进和推广了已有的结果。所考虑的非线性系统的类也扩大。仿真结果表明了该方法的有效性。
Inverse optimal control for nonlinear systems with structural uncertainty is considered. Based on the control Lyapunov function, a theorem for the globally asymptotic stability is presented. From this a less conservative condition for the inverse optimal control is derived. The result is used to design an inverse optimal controller for a class of nonlinear systems, that improves and extends the existing results. The class of nonlinear systems considered is also enlarged. The simulation results show the effectiveness of the method.
