Abstract: The controller partitioning problem for the integrated flight/vectoring propulsion control was presented in detail,and an analytical controller partitioning was obtained using a stepwise procedure.Based on the results of the analytical controller partitioning,an optimization scheme for controller partitioning using nonlinear least-squares method was proposed.The optimization scheme proposed in this paper is quite effective and easily realizable.Then,an optimal controller partitioning was obtained using the optimization scheme for the integrated flight/vectoring propulsion control.The experiments on many nonlinear simulation examples demonstrate that the performance of closed-loop system with the optimal partitioned subcontrollers is almost the same as that achieved by the centralized controller,indicating that the controller partitioning scheme discussed in this paper is quite suitable and successful.
