Abstract

This paper proposes a control framework using optimal prediction control allocation method (PM) and active disturbance rejection controller. First, the PM algorithm is adopted to extend the Attainable Moment Set compared with Pseudo-Inverse method (PI). By compensating the solution with null space vector, the saturation problem is solved while outputting the desired moments. Second, active disturbance rejection controller is adopted to observe and compensate the complex disturbance during the transition of tiltrotor aircraft. Numerical simulations demonstrate that PM can output optimal control allocation solution to generate larger moments under the same desired moments input compared with PI. The 6-DOF flight simulation shows that the overall control frame has better performance.
