- © 2013 IEEE.Consider one special closed loop system structure with one unknown plant and two unknown controllers,i.e. feed forward controller and feedback controllers, our missions are to identify this plant and design these two controllers without any physical principles. Based on the measured input-output data sequence, direct data driven scheme is proposed to achieve these dual goals. For the case of parameterized plant and two parameterized controllers, two kinds of unknown parameter vectors are estimated from the data sequence, and the iterative idea is applied to identify them recursively until to be convergence. In addition, controller validation modular is added to testify whether the designed controllers are satisfied, being from the idea of model validation in system identification. Then theoretical analysis on direct data driven scheme can be implemented to guarantee UAV flight control structure work well, bringing the detailed UAV flight control performance.
