摘　　要：敏感度是系统鲁棒特性的主要指标,对于控制对象存在较大模型化误差的伺服系统来说,必须具有低敏感度特性。本文应用二自由度控制理论和敏感度特性,设计出了对控制对象的模型化误差不敏感的低敏感度伺服系统,并采用8098单片机实现了数字化低敏感度伺服补偿器。Sensitivity is a main index of the system's robustness. The servo system which has large modelling error must be with low sensitivity. In this article, by means of the Two Degree of Freedom Control theory and sensitivity character,authors have designed a servo system with low sensitivity,which is sensitiveless to the plant's modelling error. At the same time,using 8098 single chip computer authors have achieved a numerical servo compensator with low sensitivity.
