The Nonlinear Iterative Closed Loop Configuration of Control Allocation for Aircraft with Multiple Control Effectors

The linear description and the inaccurate efficiency coefficients bring on the error of control allocation. The iterative closed loop configuration for control allocation was put forward and the nonlinear iterative method was introduced in the control allocation process. The convergence of this configuration was analyzed and simulated. The computational time was not increased and the method can solve the nonlinear control allocation problem. Results show that the iterative closed loop configuration can decrease the allocation error and enhance the robust of control allocation result to the efficiency coefficients.
