| 摘 要： | 变论域自适应模糊控制器已经成功应用在许多领域,然而它的参数难以准确估计,因此其失真率计算十分困难.本文基于Markov过程,提出一个新的计算方法.该方法通过一个特殊的Markov链模拟变论域自适应模糊控制器工作过程,解决了它的失真率计算问题,并证明这个方法是可行的.同时,通过两个算例验证这个方法的有效性.

| Abstract: | The adaptive fuzzy controller based on variable universe has succeeded in many applications,but its computation of distortion ratio was very difficult since there lacks feasible method for its parameter estimation.In this study an approach was presented based on Markov process.By simulating the performance of the adaptive fuzzy controller based on variable universe by a Markov chain,the problem of the computation of distortion ratio is solved.The feasibility of the approach is demonstrated theoretically,and the effectiveness is verified by two examples. |
