Fuzzy Adaptive Robust Control of Nonlinear Systems
一类非线性系统的自适应模糊控制

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.
