摘　　要：本文就电随动系统的奇异最优控制问题作了进一步的研究.考虑了负载力矩对于最优控制律的影响,采用观测器对分段常值型未知负载力矩进行估值,并据此在线修正最优开关曲线,从而使系统具有适应性.In this paper, the singular optimal control for DC. servosystems is concerned, the effect of load torque on the optimal control law is studied. A reduced-order observer is used to estimate the unknown piecewise-constant load torque and based on this an optimal switching surface is modified on-line so that the system is adaptable.

关 键 词：最佳控制 观测器 伺服系统
