一种新颖模糊控制器的研究

对于常规的模糊控制器而言，要提高其控制精度，常用的方法是通过增加模糊变量的语言值来获取更多的控制规则，但这会大大增加存储空间和计算时间。针对此问题，该文提出一种比例控制和模糊控制相结合的混合结构模糊控制器的设计方法。该方法通过增加一个并联的比例控制器，既保证了模糊控制器的精度和跟踪性能，又使得模糊控制器的控制规则大为简化，非常有利于实际的应用。仿真结果表明，这种控制方法简单实用，并且控制器具有非常优良的响应特性。

Study on a New Fuzzy controller

As far as the general fuzzy controller is concerned, in order to improve its performance, the measure that always be taken is to add more values of the fuzzy variables. But this method will cost more storage space and calculating time. To solve the problem, a new mixed-structure fuzzy controller that mixes the proportion controller with the fuzzy controller is presented in the paper. By adding a parallel proportion controller, the method will not only ensure the precision and tracking performance of the fuzzy controller but also reduce the controlling rulers sharply, which will be propitious to practical application. The simulation results show the method is simple and applicable. The controller's performance is perfect.
