| Abstract: | 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. |
