摘要

针对一自由度机械质量系统中存在的粘滑摩擦影响,提出了一种基于动态模糊逻辑的自适应算法。提出的控制方案是一种在线辨识和间接自适应控制,通过自适应调节控制输入来补偿非线性的影响。采用李雅普诺夫稳定性分析来保证跟踪误差、辨识误差等的有界性。在一个具有粘滑摩擦的1自由度机械质量系统上验证了该算法的有效性。

Adaptive stick-slip friction compensation using dynamic fuzzy logic system
A dynamic fuzzy logic based adaptive algorithm is proposed for reducing the effect of stick slip friction present in 1-DOF (one degree of freedom) mechanical mass system. The control scheme proposed is an online identification and indirect adaptive control, in which the control input is adjusted adaptively to compensate the effect of nonlinearity. Lyapunov stability analysis is used to ensure the boundedness of tracking errors, identification errors etc. The efficacy of the proposed algorithm is verified on a 1-DOF mechanical mass system with stick slip friction.
