Flight control based on the moment compensation and allocation for aircraft with multiple control effectors
|
Abstract:
The problems of the redundant effectors and the nonlinear aerodynamics of an aircraft with multiple controleffectors are studied. A new nonlinear flight control system design method is presented based on the control-allocation and the moment-compensation. The indirect configuration of command-moment-effectors is employed. Based on the model-following method, the outer-loop generates the moment command to meet the requirements on the flight quality. Combining the control-allocation and the moment-compensation in design, the inner-loop controls the effector deflections to implement the desired moment commands. Simulation test of the above method is carried on the innovative control effectors(ICE) aircraft. The results show that the system of moment compensation and allocation realizes the accurate tracking of desired moments; and the system shows good adaptability when the system parameters are changed. The designed flight control system can track the control-command based the reference model; and the coupling between control channels are effectively suppressed.
