茂比乌斯变换

Third , to make the vehicle meet the performance index in full flight envelop , a h gain - scheduled controller based on linear varying parameter ( lpv ) system are designed . a lpv plant with a linear fractional dependent variable can be represented by upper lft ( linear fractional transformation ) interconnection . with this technique , the overall control problem can be transformed to a traditional robust control problem , and the ultimate results are given by solving a series of linear matrix inequalities ( lmis )
通过把非线性系统简化为了线性变参数系统( lpv ) ，再有通过线性分式变换( lft )将lpv系统转化为一个线性定常系统和不确定性组成的lft互联形式，使之转换成为一个经典鲁棒控制问题，然后通过求解一组线性矩阵不等式( lmis )得到变增益h _控制器。
