Controller partitioning method for integrated flight/vectoring propulsion control

The controller partitioning problem for the integrated flight/vectoring propulsion control is presented in detail and an analytical controller partitioning is 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 is proposed. The optimization scheme proposed in this paper is quite effective and easy to realize. Then an optimal controller partitioning is 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, which means that the controller partitioning scheme discussed in this paper is quite suitable and successful.
