在动态性能指标和稳态性能指标方面,潜遗传变论域模糊控制器相对于一般模糊控制器均获得了较大的提高.这主要体现在稳态精度的提高和超调量的降低.但是,这些性能的提高与其伸缩因子的选取有很大的关系.针对不同的控制对象中,详细讨论了伸缩因子的参数对控制器动态性能的影响, 总结了参数在不同的数值区间取值时影响动态性能的规律,解决了在实际应用变论域模糊控制器时对参数取值的困难.

It is found that the fuzzy logic controller with indirectly-inherited variable universe is an improvement upon common fuzzy logic controller for both dynamic and stable performances. Its advantage lies mainly in high accuracy and slight overshoot. However, the improvement relies on the expandable and shrinkable factor. How the parameter of the expandable & shrinkable factor works on dynamic performance is discussed, the laws of dynamic performance are summarized by the adjustment of the par...
