The laser-guided projectile exhibits insufficient damping and is highly sensitive to changes of aerodynamic parameters. This paper presents a novel control structure for the laser guided projectiles, integrating a Pseudo Angle of Attack Three-Loop Autopilot (PAA-TLA) with Adaptive Disturbance Rejection Control (ADRC). Dynamic performance of the guided projectile is thoroughly examined under open-loop body flight conditions, as well as when subjected to control loops including damping, stabilization and PAA-TLA. The result indicates that, with varying parameters selections, the new system structure can be equivalent to PAA-TLA or a first-order inertial system. It can achieve either strong anti-jamming capabilities or fast, stable response performance for different operational requirements.

摘要

The laser-guided projectile exhibits insufficient damping and is highly sensitive to changes of aerodynamic parameters. This paper presents a novel control structure for the laser guided projectiles, integrating a Pseudo Angle of Attack Three-Loop Autopilot (PAA-TLA) with Adaptive Disturbance Rejection Control (ADRC). Dynamic performance of the guided projectile is thoroughly examined under open-loop body flight conditions, as well as when subjected to control loops including damping, stabilization and PAA-TLA. The result indicates that, with varying parameters selections, the new system structure can be equivalent to PAA-TLA or a first-order inertial system. It can achieve either strong anti-jamming capabilities or fast, stable response performance for different operational requirements.
