Research on Control Method of Small Turbofan Engine Based on Lyapunov Function

In order to solve the problem of poor signal tracking and system robustness encountered in the control system design of DGEN380 turbofan engine, this paper uses a nonlinear model with general nonlinear terms to describe the dynamic process of the engine model at a certain working point based on DGEN380 turbofan engine. The Lyapunov direct method is used to construct the lyapunov function to design and simulate the nonlinear control of the nonlinear turbofan engine model. The simulation results show that the designed controller can greatly improve the response speed of the system under the premise of ensuring the stability of the system, and the system has good tracking and robustness.
