Attitude Control of a Fin-Stabilized Projectile on a Three-Axis Gimbal in Wind Tunnel

In this paper, a three-axis autopilot has been developed for a guided projectile steered in a wind tunnel. A linear model based on the equations of motion is identified using parameter estimation methods. Then, a fixed-order controller is synthesized in a multi-objective framework and implemented on a dual-loop structure. The reference tracking performance and disturbance rejection capabilities of the closed-loop plant are evaluated by dedicated experiments and compared to the model predictions.
