基于DMC-PID串级控制的无人机迎角自动控制系统

UAV Angle of Attack Automatic Control System Based on DMC-PID Bunches Control Technology

预测控制是近年来在工业过程控制中得到广泛重视和应用的一类新型计算机控制算法。它有良好的动态响应、跟踪性能和鲁棒性,但抗干扰性不够理想。介绍了将DMC-PID串级控制技术应用到无人机无动力飞行时的自动着陆阶段迎角自动控制系统。仿真结果表明,DMC-PID串级控制系统总体性能上优于PID-PID串级控制系统,集中了预测控制系统和PID控制系统的优点。

Predictive control is a new type of computer control algorithms being widely noticed and used in industrial process control. It has good dynamic response, tracking performance and robustness except suppressing disturbance. DMC-PID bunches control technology in the angle of attack automatic control system during unpowered flying automatic landing period is introduced. The simulation indicates that DMC-PID bunches control system performs better than PID-PID bunches control system in the whole performances and collects the strongpoints of predictive control system and PID control system,
