- Abstract
A method for designing switching control of a one-spool aircraft engine is proposed. The method can decrease switching frequencies among the models. Firstly, a Lyapunov approach is used to stabilize the nonlinear control system by choosing a suitable set of control parameters, leading to nonlinear model-based acceleration control. Then switching-based acceleration control is obtained for the two operating points. Simulation results show that the performance of the nonlinear model-based acceleration control is better than that of the switching-based control. Meanwhile, the former method uses only one nonlinear model, avoiding the model switching problem that is encountered in the switching-based method. The correctness of the proposed design method is thus validated.
