摘要
针对一类非线性系统,利用模糊逻辑提出一种鲁棒自适应控制方法.首先证明在一定的条件下,闭环系统必能稳定,并证明这个条件即必落人某一紧集中成立,同时考虑其控制性能,选择鲁棒控制量,使跟踪误差达到要求的性能指标.
For a class of unknown nonlinear systems,this paper presents a fuzzy adaptive robust control scheme, we first prove that the closed-loop system must be stable under a certain condition,then we prove the condition that the state x of the system falls into a compact set at all time,moreover,considering the control performance,we select a robust control value to attenuate the effect of both the external disturbance and fuzzy approximation error to a prescribed level.
