摘　　要：该文针对小型涡扇发动机的强非线性的特点,在状态空间模型基础上引入非线性项,在传统的滑模控制基础上引入状态动态补偿,基于非线性模型设计了稳态调节控制器和输出转速跟踪控制器,在理论上证明了该设计方法的有效性,研究表明上述控制器响应速度快、控制鲁棒性好。并以DGEN380发动机为仿真研究对象,对上述控制器进行仿真,仿真结果验证了该设计方法的有效性。For the strong nonlinear characteristics of small turbofan engines,nonlinear terms are introduced based on the state space model. State dynamic compensation is introduced on the basis of traditional sliding mode control. A steady state regulation controller and an output speed tracking controller were designed. Theoreti cally proved the effectiveness of the design method. Research shows that the above controller has fast response and good control robustness. The above controller was simulated with the DGEN380 engine as a simulation study object. Simulation results verify the effectiveness of the design method.
