Abstract :
This paper deals with the design of robust digital controllers for gun-turret systems which exhibit large parameter and high frequency unmodeled uncertainties. A method based on quadratic stability criteria is developed to search control laws which achieve possible maximum tolerance for system uncertainties while remaining high degree of tracking and reulating precision. Simulated results are shown and the superiority of the proposed method is demonstrated.
