The controller to be designed is assumed to have state feedback gain variations. Design methods are presented in terms of linear matrix inequalities (LMIs).
假定所要设计的控制器存在状态反馈增益变化，设计方法是以线性矩阵不等式组的形式给出的。
It is obtained by numerical calculation that the mode spot size at the mirrors in a resonator with arbitrary configuration is always a finite value as long as radial gain variations are present.
只要出现径向增益变化，通过数值计算得到任意结构的谐振腔腔镜处的光斑尺寸总是有限值。
Farmers can lose rather than gain if incomes fluctuate because of variations in crop yields and outputs-stable prices can then destabilize incomes.
农作物产量和产值的变化如果引致收入波动，这对农民来说就可能是有害无益，因为稳定了价格可能稳定不了收入。
