Applying a direct identifier-based adaptive strategy for enhancing line-of-sight control

This article presents the control of line-of-sight for two-DOF gimbal system. To improve the performance system, the direct identifier-based adaptive controller is proposed. In this strategy, the parameters of controller polynomials are calculated through recursive least square. With respect to the obtained polynomials, the control signal is implemented for both elevation and azimuth axes. This approach is applied to track a target in 3D spaces for two-DOF gimbal system and test both the axes. The simulation results confirm the efficiency of this purposed controller and satisfy the tracking a given target.
