含结构不确定系统的变结构鲁棒自适应控制
Variable Structure Robust Adaptive Control with Unmodelled Dynamics
-
摘要: 讨论了含结构不确定SISO系统的变结构模型参考鲁棒自适应控制问题,提出了 一种新的变结构控制方法,使得:1)系统在同时含参数及结构不确定性时,跟踪误差仍能在有 限时间内收敛到零;2)无须假设参考模型为SPR(严格正实)函数.理论分析与数值仿真结果 是一致的.Abstract: In this paper, a new variable structure robust model reference adaptive control (VSMRAC) scheme is proposed, which deals with a class of SISO plants under parameter and unmodelled dynamical uncertainties. It is shown that even with the existence of unmodelled dynamics, the output tracking error will converge to zero in finite time, and the SPR(strictly positive real)condition for reference model is not required. Numerical simulation is provided to support the theoretical developments.
