In this research, GPC Control is proposed for the control of a stabilizing loop from a two axis gimbal seeker. In fact,
there are some views about using GPC type controller which are twofold. First, it drives the stabilization loops that
are made by a DC motor, Rate Gyro, inertia and cross coupling unit in between two channels using the predictive model
type controller. Second, the theory is to excavate the results of flight simulation on the efficiency of two-axis gimbal
seeker. The simulations, based on different scenarios, are valuated for the proficiency of the designed system
considering the dynamic mass imbalance and the cross-coupling in between two channels and the flight simulation. The
flight simulation results are explained the accuracy of the designed system with predictive control in opposite of
conventional PI controller. For example, the simulation results in Altitude = 2km show the suggested system in
comparison with conventional PI controller improves miss-distance and flight time 11.98% and 1.5% respectively.
Moreover, the suggested system in maximum control signal = 72.61%, minimum control signal = 1.55% and final time =
80.43% (control effort parameter), is better than PI type controller.
