该技术区别于传统增益调度技术的关键在于其能够在设计过程中对时变参数进行处理,直接生成全局线性参数时变(LPV)控制器,从而很好地克服了传统增益调度技术对控制器复杂程度的限制以及局部特性与全局特性不一致等问题。

当模型复杂且非线性时(换句话说,在线性方式下参数不共变),或者当模型涉及多于两三个不确定参数时,使用该方法。
The method is used when the model is complex and nonlinear (that is, parameters do not co-vary in a linear manner), or when the model involves more than just two or three uncertain parameters.
