摘要
研究前件变量采用双交叠模糊分划的T-S模糊系统的稳定性问题.首先针对自由系统,将连续时间系统的、基于最大交叠规则组的稳定性分析方法推广应用于离散时间系统,并采用模糊Lyapunov方法得到了稳定性的新结论.采用非并行分布补偿控制律,针对受控系统也得到了相应的结论.这些结论比已有的结果更加宽松.仿真例子验证了该稳定性结论.
The stability is studied for fuzzy systems with their premise variables employing two-overlapped fuzzy partition. For autonomous systems, the stability analysis method of continuous systems is generalized to discrete time systems based on the maximal overlapped-rule group, and the fuzzy Lyapunov method is applied to obtain new stability results. By applying the non-parallel distributed compensation law, the corresponding results are obtained for controlled systems. The results are less conservative than existing ones. A simulation example shows the stability results.
