| 摘 要： | 将多幂次滑模趋近律用于航空发动机控制,设计了基于滑模控制方法的航空发动机追踪控制器。针对多幂次滑模趋近律在航空发动机追踪控制中出现的高频振荡问题,提出了一种改进的多幂次滑模趋近律。基于改进多幂次滑模趋近律的追踪控制仿真表明,改进的多幂次滑模趋近律适用于航空发动机追踪控制,该方法不仅具备了多幂次滑模趋近方法响应速度快、鲁棒性好的优点,而且消除了控制中的高频振荡现象。

| Abstract: | An improved sliding mode control algorithm is applied to aeroengine control, for which the controller is designed that based on sliding mode control. An improved multi power reaching law of sliding mode control is proposed in this paper, which aims at reducing high frequency oscillation phenomenon appeared in multi power tracking control process of aero engine. The proposed reaching law is used in simulation of aero engine control system, whose results show that the proposed reaching law is applicable for tracking control of aero engine. Not only does the proposed reaching law has these advantages that are fast response speed and strong robustness but also it can eliminate high frequency oscillation phenomenon. |
