Adaptive Fuzzy Sliding Mode Control for Electro-hydraulic Position Servo System

摘要：

An adaptive fuzzy sliding mode control (AFSMC) for Electro-hydraulic position servo system is proposed in this paper. Based on Lyapunov stability theory, the adaptive fuzzy algorithm with parameter online adjusted function is derived to approximate the equivalent control of sliding mode, and the nonlinear control part is also determined, so that system tracking stability can be guaranteed whether the uncertainties exist or not. Four items of fuzzy rules based on sliding mode control (SMC) are presented to smooth the chattering. The experiment results show that the high adjusted accuracy by AFSMC makes the system possess strong robustness and high stability, meanwhile the chattering phenomenon of the control effort is also suppressed effectively.
