The objective of this research work is to design and implement control algorithms for smart fin of a projectile, which is currently under development in the Army Research Laboratory (ARL). The smart fin is used to maneuver small aerial vehicles by controlling the rotation angle of the fin. The fin is activated by a composite laminated plate that has two active piezoelectric layers. The prototype of the smart fin is assembled using Macro Fiber Composite (MFC actuator model M8557, Smart Material Co); Control algorithms for rotating the fin when subject to external aerodynamic forces are proposed. These controllers use a finite element model of the system. The three controllers are designed using Integral, Adaptive and Fuzzy Logic techniques respectively. Effects of Aerodynamic forces and uncertainties are included in these controllers; An experimental setup of the fin and actuator has been made for verifying and implementing the controllers with a real-time controller (dSPACE DS1102 controller board), which can be interfaced with the code developed in MATLAB and Simulink. Final tuning of the model is done using experimental data.
