Abstract

Abstract

Taking the simple model of an alternating current torque servo system as the control object, a 2-degree of freedom inner model controller based on the H_∞ robust controller is devised. Emulation experiments show that compared with a traditional controller both the traceability and robust stability of the new system are improved under variation of parameters, and the negative effect of the variation of parameters is limited.
