一种新的自调整因子的模糊控制器的仿真研究

The Simulation of Fuzzy Controller With A New adjustable Factor

在模糊控制规则的构造中,带有多个调整因子的模糊控制规则虽然比较灵活,方便,但是对多个调整因子的寻优要花费较大的计算量,因此难以实时实现.尤其是随着误差,误差变化及控制量的论域量化等级的增加,调整因子的个数也相应增加,使得寻优过程变的复杂.一方面要考虑吸取带多个调整因子的优点.另一方面又要考虑尽量简化寻优过程.更好的满足实时性要求。因此本文设计了一种在全论域范围内带有自动调整因子的控制器.提出了一种新的控制算子,并对一二阶对象进行了仿真试验,获得了良好的控制效果.

Although Fuzzy Control rules with several factors is flexible and more adjustable,but the optimisation of The factors will take up a lot time , especi ally with the increasing of the grade in error and error.deritive, the number o f factors is increasing ,which lead to the complexion of optimisation, in order to take the merit of factors and simplify the course of optimisation . In this e ssay the author design a controller, whose factor can be adjusted in the whole f ield, By making a simulation on a two-order plant, it takes out a good result.
