摘要
研究了一类模糊双线性跳变系统的随机镇定问题.采用T-S模糊建模技术来构建模糊双线性跳变模型,然后通过并行分布补偿(Parallel distributed compensation,PDC)方法和选择合适的模糊隶属度函数,将整个非线性控制器表示为一组局部线性控制器的模糊综合.此外,还推导出了保证闭环模糊双线性跳变系统随机稳定的充分条件,并且这些条件最终可归结为一组线性矩阵不等式(Linear matrix inequalities,LMIs)的可行性问题.最后,连续搅拌反应釜(Continuous stirred tankreactor,CSTR)系统的数值示例表明该设计方法的合理性和有效性.
This paper deals with the problem of stochastic stabilization for a class of fuzzy bilinear systems with Markovian jump parameters.The Takagi-Sugeno(T-S) fuzzy modeling technique is adopted to construct a fuzzy bilinear jump model.By means of the parallel distributed compensation(PDC) method,an overall nonlinear controller is constructed by blending a set of local linear controllers through selected membership functions.Besides,some sufficient conditions are derived to guarantee the stochastic stability of the closed-loop fuzzy bilinear jump system via linear matrix inequalities(LMIs).Finally,a numerical example for a continuously stirred tank reactor(CSTR) system is given to illustrate the validity and effectiveness of the designed procedure.
