航空发动机变结构全局快速Terminal滑动模态控制方法研究

Aero-engine Variable Structure Global Fast Terminal Sliding Mode Control Method

针对航空发动机这个具有时变不确定性的非线性系统,提出了一种新型变结构全局快速最终滑动模态控制(Variable Structure Global Fast Terminal Sliding Mode Control)的航空发动机控制方法;通过对利用VSGFTSMC理论设计航空发动机最终滑动模态控制器的方法进行了深入研究,设计了航空发动机变结构全局快速滑动模态控制器;仿真结果表明,所设计的控制器的控制效果良好,对外界干扰有很强的抑制能力,使被控系统在整个控制阶段都具有较强的鲁棒性。

A new kind of aero--engine control method based on the variable structure global fast terminal sliding mode control is proposed for the varying uncertainty nonlinear system of aero-- engine. The aero-- engine global fast terminal sliding mode variable structure controller has been designed by the in--depth study of VSGFTSMC theory. The simulation results show that the designed controller has good control effect and strong suppression of external interference, so that the controlled system has strong robustness in the entire control stage.
