Roll stabilization: a higher-order sliding-mode approach

The robust stabilization of roll angle for PGM-class missiles (precision guided missiles) is considered in this paper. The roll dynamics in these missiles are stable but have large parametric variations and slow response behavior. A novel method for roll-angle stabilization using higher-order sliding-mode control with actuator saturation is proposed in this paper. The actuator and sensor dynamics are considered, and the controllers are designed to meet specifications in the presence of these dynamics.
