A New Adaptive Control Technique,

Abstract

An adaptive controller is synthesized in response to requirements exposed by a study of a low-order unstable mechanical system driven by a bang-bang actuator. The subject plant consists of a rigid rod pinned to a motor-driven cart; a mass mounted somewhere on the rod constitutes the unknown parameter in the system. The goal is to synthesize control logic which can cope with the unknown mass locations and stabilize the system from all potentially controllable initial conditions. The evolved adaptive technique differs from previously developed methods in that adaption takes place during chatter motion of the controller. These developments arose from study of a higher-order mechanical system whose equations of motion are similar to those describing the planar motion of an aerodynamically unstable missile. The technique appears to be applicable to missile control and generalizable to an even broader class of systems. (Author)
