提高模糊控制器控制性能的一种实用方法

A Utility Method of Improving Control Performance for Fuzzy Controller

针对常规模糊控制器存在稳态误差的缺点,分析了其存在稳态误差的原因,又指出了其在响应时间、鲁棒性等指标上需要进一步改善的问题,由此提出了一种提高模糊控制器控制性能的实用方法。仿真结果表明,此方法可以消除稳态误差、缩短系统的响应时间、使系统的鲁棒性得以进一步的改善,其动态性能也有了明显的提高;工程实践证明,此方法易于实现,控制效果良好。

Aimed at the shortcoming of conventional fuzzy controller have static error, the reason of existing it is analyzed, and points out that the questions must be amended about respond time and robust, there by puts forward a utility method to improve controlling performance of fuzzy controller. The simulation studies show that this method can eliminate static error and improve respond time of control system, more amend robust and dynamic capability. It is proved that this method is realized easily in engineering practice and has better control effect.
