摘要

本文提出了一种针对两个输入通道的非齐次动态模糊控制器的系统开发方法;所提出的控制器结构适用于一类二阶和三阶对象,这是特定于电驱动领域的。电驱动的特点是标准模型,即使是经典的(线性)控制结构给予满意[ast95]。这种设计关系是基于模糊控制器在某些条件下可以被线性控制器很好地逼近,因此扩展对称最优方法[pre96]适用于这种情况。基于数字仿真结果的详细分析表明,与其他包含常规控制器的结构相比,所提出的模糊控制器可以确保更好的控制系统相对于参考输入的性能。

Development of some fuzzy controllers with non-homogenous dynamics with respect to the input channels meant for a class of systems
The paper presents a systematical development method for four fuzzy controllers with non-homogenous dynamics with respect to the two input channels; the proposed controller structures are meant for a class of second order and third order plants, which is specific to the field of electrical drives. The electrical drives are characterized by standard models for which even the classical (linear) control structures give satisfaction [ast95]. The design relations result on the basis of the fact that fuzzy controllers can be, in some certain conditions, well approximated by linear controllers and, so, the Extended Symmetrical Optimum method [pre96] is applicable in this situation. A detailed analysis based on digital simulation results proves that the proposed fuzzy controllers can ensure better control system performance with respect to the reference input in comparison with other structures containing conventional controllers.
