The LQ-Design Method for the Strong Disturbance Resistibility of D.C.Speed Control Systems

In this paper,a technique for the improvement of the dynamic disturbance rejection of D.C.speed control systems is discussed.The proposed new compensator transient compensator can strengthen the dynamic disturbance rejection effectively when some physical constraints in amplitude are imposed on the feedback gain coefficients.An Inverse Linear Quadratic design method is introduced and the digital simulation results of the system disturbance rejection response is given.
