摘要
利用控制Lyapunov函数的新特性,对非线性仿射系统进行了逆最优控制器的设计,进一步改进了基于控制Lyapunov函数的控制器的性能,并且该控制器对于一定范围的输入不确定性具有鲁棒性。将结论用于陈氏混沌系统不稳定平衡点的渐近稳定控制律的设计中,理论分析与仿真结果证明了该方法的有效性与实用性。
An inverse optimal controller is designed for the nonlinear system by employing new characteristic of control Lyapunov function(CLF), which further improves the performance of CLF design methods, and the controller is shown to be robust to some input uncertainties. With this method, a control law is designed for Chen's chaotic system to make it globally asymptotically stable on one of its equilibrium points. The theorical analysis and practice illustrate the effectiveness of this method.
