有死区输入的非线性确定系统的自适应控制

Adaptive Control of Nonlinear Determining System with Dead Zones Input

通过应用模糊逻辑系统逼近非线性函数,研究一类具有未知死区和外部扰动的非线性系统的自适应模糊控制问题。设计适当的虚拟控制函数和自适应率,解决未知死区和外部扰动问题。利用反推技术,设计了一种新的自适应模糊控制方案,该方案保证了闭环系统的所有信号是有界的,并且跟踪误差收敛到原点的小邻域。

By applying a fuzzy logic system to approximate a nonlinear function, a class of adaptive fuzzy control problems for a class of nonlinear systems with unknown dead zones and external disturbances is studied. We design appropriate virtual control functions and adaptive rates to solve unknown dead-zone and external disturbance problems. Using the backstepping technique, a new adaptive fuzzy control scheme was designed. This scheme ensures that all signals of the closed-loop system are bounded and the tracking error converges to the small neighborhood of the origin.
