本文针对电液位置伺服系统本身固有的非线性等特点,设计和实现了一种仿人智能型模糊一自适应控制器。仿真和实验结果表明,该方法能显著地改善系统的动态特性,提高了稳态定位精度,有效地克服非线性等因素的影响,且对参考模型不敏感,表现了较强的鲁棒性。
In this paper, aiming at the inherent non-linearity and other characteristics of the electrohydraulic servo system, a humanoid intelligent fuzzy-adaptive controller is designed and implemented. Simulation and experimental results show that this method can significantly improve the dynamic characteristics of the system, improve the steady-state positioning accuracy, effectively overcome the influence of nonlinear factors, and are insensitive to the reference model, showing strong robustness.
