Synthesis of a hybrid super-twisting and adaptive fractional-order sliding-mode control law for the gimbal seeker ensuring disturbance rejection and high accuracy
This paper investigates the synthesis of an Adaptive Fractional-Order Super-Twisting Sliding Mode Control (AFOSTSMC) law to improve line-of-sight (LOS) stabilization performance for the two-axis gimbal drive system of an electro-optical seeker. The gimbal system has strongly nonlinear dynamics and is affected by angle-...
