| 摘 要： | 以涡扇发动机参数限制保护为目标设计了一种滑模(SM)调节器.采用区域极点配置的混合范数综合法设计了滑模调节器的反馈增益系数；根据全局渐近稳定性判据验证了本滑模控制仿真的稳定性；基于滑模调节器在仿真环境中进行了控制系统的建模，对不同的滑模可调参数切换增益进行了比对分析，并选取了某一组切换增益值作为后续仿真的基准参数；仿真对比分析了滑模调节器和线性调节器的调节效果.结果表明:基于滑模控制方法所设计滑模参数限制调节器在发动机过渡态过程中对发动机进行主控，克服了线性参数限制调节器在过渡态过程几乎无法实施控制的缺点； 该设计的滑模参数限制调节器能在7s内实现发动机过渡态的参数限制保护功能.

| Abstract: | A sliding mode (SM) regulator was proposed for the turbo fan engine parameter limit protection. The feedback gains of the SM were designed using the regional pole placement method based on the mixed norm synthesis. The overall asymptotic stability of the SM regulator was established. The SM regulator was verified and compared in the simulation with different sliding switch gains, of which one of the gains was used as the standard coefficient for the following simulations. The regulating effects between SM regulator and linear regulator were compared and analyzed. The results preliminarily show that, the parameter limit regulator acts as a main control regulator during engine transient state process based on sliding mode control theory, overcoming the drawback of linear parameter limit regulator which nearly can not work during the same process; the designed regulator can conduct the parameter limit protection function in 7 seconds during the engine transient state. |
