摘要
针对一类控制方向未知且具有未建模动态的非线性系统,提出了一种鲁棒自适应控制策略。算法推广了已有的鲁棒自适应非线性控制方法。控制算法保证闭环系统所有信号是一致终值有界的。同时,通过调整控制器设计参数,闭环系统能够实现期望的性能要求。仿真结果进一步说明了理论分析的有效性。
A robust adaptive control scheme was proposed for a class of nonlinear systems with unknown control direction and unmodeled dynamics, The proposed design method expands the class of nonlinear systems for which robust adaptive control approaches have been studied. It is proved that under the proposed control law, all the closed-loop signals are uniformly ultimately bounded and the prescribed control performance can be guaranteed by an appropriate choice of the design parameters. Simulation study is provided to illustrate the effectiveness of the proposed algorithm.
