Abstract:

A control method for a unmanned aerial vehicle having large aspect ratio is proposed. A compensative controller is designed based on dynamic projective control method and robustoptimal theories. Firstly, a closed loop system of robust servomechanism linear quadratic regulator method is obtained by state feedback which is considered as a reference system. Then a method of dynamic projective control is adopted to reconstruct the whole characteristic structure of the reference system by output feedback and a dynamic compensator. The concrete steps of the pole placement by dynamic projective control method are expounded. Also, the influence of varying the free matrix of dynamic compensator is discussed. The result of simulation shows that the designed control system has remarkable transient performance and stability which is much better than ordinary control method.
