Research on Servo Control Strategy Based on Fuzzy Adaptive Fractional PI~λ

本文提出以传统PI控制器为基础，结合广泛应用的模糊控制理论以及迅猛发展的分数阶控制理论，设计一种基于模糊自适应分数阶PIλ的伺服控制器的设想，并在Simulink中搭建仿真模型验证其控制性能。仿真结果显示，本文设计的伺服控制器表现出更为优越的性能。对于高精度伺服系统而言，模糊自适应分数阶PIλ控制器能够满足其对控制性能的苛刻要求，具有一定的可行性。

This paper put forward a vision that designing a fuzzy adaptive fractional PI λ controller based on the traditional PI control combining the widely used fuzzy control theory and the fast developing fractional theory. Meanwhile dynamic simulation for the feed servo system is done under the SIMULINK, which results show that the servo controller designed in this paper has superior control performance and the adaptive fuzzy fractional PI λ can meet the control requirements of high precision servo system. The idea is feasible.
