| 摘 要： | 为了有效对某型航空发动机进行控制,首先对其过渡态的各状态段的实验数据,基于系统辨识的理论,按照预处理、辨识、验证的步骤求取其传递函数;考虑到发动机过渡态状态变化大,故利用鲁棒性强、能克服对象参数变化的H∞控制方法来进行控制系统的设计,并引入前馈比例控制器对控制结构进行变形,以克服H∞回路成形控制超调量大的缺陷;仿真结果表明辨识数据与原始数据的拟合度能够达到82.99%,鲁棒控制器在发动机状态大范围变化时仍能拥有不错的控制效果,调节时间1秒左右。

| Abstract: | Based on the experimental data of aero-engine transient state and the theory of system identification,the transfer function has been identified according to the procedure of pretreatment,identify and verify.The state of aero-engine is different during the whole transient state,so H∞ control has been used for controller design because of its well robustness,and the transfigured control structure has been presented with the application of the feedforward proportion controller in order to improve the tracking performance.The simulations show the identification results could well fit the raw data,and the designed controller could deal with the change of aero-engine state. |
