参数自调整Fuzzy+I调节器

Parameters Self-Adjusting Fuzzy+I Controller

本文针对常规模糊控制系统存在稳态误差、对设定值的跟踪性能差等缺陷,提出一种参数自调整Fuzzy+I调节器,用智能积分器来消除稳态误差、在线自调整调节器参数以改善动态特性.计算机仿真表明这种调节器有良好的动态特性、静态特性与很强的鲁棒性.

In conventional fuzzy control systems, there are some defaults or shortcomings, such as the static errors, the inefficient performance of tracing set point. In order to solving the problem, this paper presents a parameters self-adjusting Fuzzy+I controller. Its intelligent integerator eliminates the static error, parameters self -adjusting on-line of the fuzzy controller improves the dynamic character. Computer simulations show that the controller has better static characters, dynamic characters and strong robustness.
