Abstract: For anti-tank missile,this paper presents a selftuning controller by means of normal-ized model and weighting self-tuning control method.An auto-regulation weighting factor is inroduced into the generalized minimum variance self-tuning control law in order to take account of both the stability aid the dynamic index of the system and fit in with the needs of the control for the fast time-varying plant like anti-tank missile,The digital simulation shows that the controller is satisfactory for anti-tank missile.The controller has simple algorithm and stronger robustness for nonlinear,mismatched order and unmodeled disturbance of the Drocess.
