Theory of Disturbance-Utilizing Control With Application to Missile Intercept Problems.

Abstract

Control problems with disturbances which have waveform structure may be addressed by considering the maximum utilization mode of disturbance-accomodating control theory. It is shown in this work that the optimal utilization of disturbances can lead to significantly better performance than that of the 'optimal' linear-quadratic regulator. The conditions for the existence of a steady-state disturbance-utilizing control law are derived. It is shown that the steady-state control gains when they exist, are solutions of certain matric algebraic equations. Steady-state gain expressions are derived for several first- and second-order plants. Results are presented for the cases of optimal disturbance-utilizing control of an air-defense interceptor missile and of a missile homing on a fixed target, which demonstrate performance superior to that obtained by a conventional 'optimal' linear-quadratic missile controller.
