针对不确定分数阶混沌系统，提出了一种新的自适应模糊控制器（FLC），该控制器采用自适应算法实现H∞同步性能。为了处理高水平的不确定性和有噪声的训练数据，可以通过结合模糊控制设计和H∞跟踪方法将所需的同步误差衰减到规定的水平。基于Lyapunov稳定性判据，该方法不仅在可接受的同步误差水平上具有令人满意的性能，而且还进行了相当简单的稳定性分析。仿真结果表明了所提控制方案的有效性。
This paper presents a novel adaptive fuzzy logic controller (FLC) equipped with an adaptive algorithm to achieve H∞synchronization performance for uncertain fractional order chaotic systems. In order to handle the high level of uncertainties and noisy training data, a desired synchronization error can be attenuated to a prescribed level by incorporating fuzzy control design and H∞tracking approach. Based on a Lyapunov stability criterion, not only the performance of the proposed method is satisfying with an acceptable synchronization error level, but also a rather simple stability analysis is performed. The simulation results signify the effectiveness of the proposed control scheme.
