DESIGN OF A DIGITAL CONTROLLER FOR GYRO STABILIZED SYSTEM THROUGH ANALOG TECHNIQUES

Abstract

This dissertation describes the control design of an electro optical stabilization system for a mobile weapon control system. Classical control laws were applied to an existing weapon system at the hardware level to optimize plant performance in the presence of certain nonlinearities and mechanical resonance constraints. Though an analog compensating network design enabled us to develop highly accurate, fast response weapon control system, it imposed serious limitation due to environmental changes and even when there was a minor change in the plant dynamics. This gave an option to convert the analog controller to digital controller so as to enable the system to work satisfactorily in the varying dynamic and environmental conditions.
