针对扰动集为时变和非时变的情况,研究具有线性分式传递函数的结构不确定性系统的模型有效性分析问题,这里讨论的模型集的不确定性比文献[1,2]讨论的要大,但计算复杂性与文献[1]相当。将这类模型的有效性分析问题转化为规划问题,并利用遗传算法进行求解。 Aiming at the time-varying and non-time-varying perturbation sets, the problem of model validity analysis of structural uncertainty system with linear fractional transfer function is studied. The uncertainty of the model set discussed here is more discussed in [1,2] Is larger, but the computational complexity is comparable to [1]. The validity analysis of such models is transformed into planning problems and solved by genetic algorithm.
