Improved Antiskid Braking Control Algorithm and System Design for Unmanned Aerial Vehicle

To satisfy landing and braking operations for un-manned aerial vehicle, an improved antiskid braking control algorithm and system that fits working characteristics is proposed together with key technical problems. Firstly, system identification and principle are introduced. Secondly, landing gear and braking apparatus of aerial vehicle are analyzed and modeled based on structural features. Electromechanical actuator active suspension force control method is used for high-precision tracking. Multi-gate threshold PD-PBM anti-sliding algorithm fused with a compensation factor for balanced adjustment is proposed to improve braking performance. Finally, proposed algorithm is verified based on single-wheel co-simulation platform and multi-wheel flight dynamics real-time view software platform.
