Robust and Adaptive Guidance and Control Laws for Missile Systems

Abstract

The objective of this three year study is to develop robust and adaptive guidance and controls laws for homing missiles, mechanizable with near- future computer technology, which can satisfy system objectives in the presence of large uncertainties and nonlinearities. Over the past years, considerable progress has been made in resolving some of the fundamental issues in homing guidance. Of particular importance, new filter structures which were tailored to the passive homing engagement, and new target models and kinematic pseudo- measurements, which modified the new filter algorithm and induced a new adaptive homing guidance law, were developed. During the last three years in support of these important innovations, robust filters and control schemes which further enhance system performance were developed based upon a stochastic control problem known as the linear-exponential-Gaussian-problem and a related deterministic approach called the disturbance attenuation problem. Most important, emerging from this work is a new structure for adaptive control and a unifying framework for developing midcourse and terminal homing missile guidance schemes under uncertainty.
