H∞ Structured Controller Synthesis Applied to Flight Controller of QTW-UAV Using Meta-Heuristic Particle Swarm Optimization

Structured H∞ controller synthesis using particle swarm optimization has been designed in control augmentation system of quad tilt wing unmanned aerial vehicle. It has been aimed to search for the existence of the optimal and practical controller feedback gains within the variations of the relaxation of H∞ constraints for longitudinal motions. The optimization results were achieved in both minimize the maximum real parts of closed-loop eigenvalues and performance indexes in order to verify the validity of the proposed method.
