FUZZY—PI控制器在双闭环串级调速系统中的应用

Application of Fuzzy-PI controller in dual loop serial speed varing system

针对传统的双闭环调速系统存在的问题,利用模糊控制和常规PI控制的优点,设计出一种参数自调整FUZZY—PI调节器,作为双闭环串级调速系统的速度调节和电流调节器。阐述了FUZZY—PI控制器的控制策略和实现方法。通过实验证明该系统对系统的非线性、参数变化及负载扰动提供了快速的鲁棒控制,并解决了稳态精度问题,实现了无静差调速。

By synthesizing the merits of Fuzzy control and usual PI control, a dual coop serial speed varing system with fuzzy- PI controller was designed. The control tactic and its implementation were described. The experimental results show that this system possesses excellent static and dynamic characteristics.
