Computation of distortion ratio of adaptive fuzzy controller based on variable universe
变论域自适应模糊控制器失真率的计算

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.
