摘要

针对一类典型的具有滞后特性的非线性系统，提出了一种自适应逆控制方法。提出了滞后算子的逆函数，并建立了逆非线性模型。在此基础上，简化了滤波LMS算法的结构，建立了一种新的自适应逆控制系统，降低了非线性，实现了精确的跟踪控制。仿真结果验证了该方案的有效性。

Adaptive Filtered-epsilon Inverse Compensation of a Nonlinear System

An adaptive inverse control approach is put forward to control a kind of typical nonlinear system with hysteresis characteristic. An inverse of the hysteresis operator is proposed and the inverse nonlinear model is built. Then the structure of filtered- LMS algorithm is simplified and a new adaptive inverse control system is built to reduce the nonlinearity and achieve accurate tracking control. Simulation results illustrate the proposed scheme's effectiveness.
