研究了集总线性时不变反馈系统在面对对象不确定性时的稳态性能。这里考虑的植物不确定性是输出端口的乘法摄动。得到了各种鲁棒稳态性能的充分必要条件。在充分必要条件下，得到了控制器结构实现各种鲁棒稳态性能的内模原理式结果。将条件转化为mu的度量，从而使控制器在mu综合和广义H/sup∞/控制理论的框架下实现鲁棒稳态性能。<<ETX>>
The steady-state performance of lumped LTI (linear time-invariant) feedback systems in the face of plant uncertainty is considered. The plant uncertainty considered here is the multiplicative perturbation of the output port. The necessary and sufficient conditions for various robust steady-state performances are obtained. Internal-model-principle-like results on the structure of controllers achieving various robust steady-state performances are derived from the necessary and sufficient conditions. The conditions are transformed into the measure of mu , thus enabling the synthesis of controllers achieving robust steady-state performance in the framework of mu synthesis and the generalized H/sup infinity / control theory.<<ETX>>
