Abstract
Based on the variable structure model reference adaptive control (VS-MRAC) theory, a new control system for the control of a projectile fin using a piezoelectric actuator is designed. The hollow projectile fin is rigid, within which a flexible cantilever beam with a piezoelectric active layer is mounted. The model of the fin-beam system includes the aerodynamic moment which is a function of angle of attack of the projectile. The rotation angle of the fin is controlled by deforming the flexible beam which is hinged at the tip of the rigid fin. For the derivation of the control law, its is assumed that the parameters in the model are unknown, and only the fin angle is measured for feedback. It is shown that, in the closed-loop system including the VS-MRAC system designed using bounds on uncertain functions, the fin angle tracks the reference trajectory and the vibration is suppressed. Digital simulation results show that the closed-loop system has good transient behavior and robustness to the uncertainties , unmodeled dynamics and disturbance inputs.
