| 摘 要： | 研究了一种自调节趋近律的滑模变结构控制器,以切换函数s作为偏差,趋近速度由一个PID控制器调节,目的是使到达滑模面的穿越速度最小从而减少抖振,同时使到达滑模面时间最短.根据航空发动机稳态数学模型,设计其滑模变结构控制律,构建了基于PXI总线的发动机滑模控制平台.通过半实物实验结果证明,该控制器响应速度快,高频抖振很小,具有很强的鲁棒性能和跟踪性能.

| Abstract: | A sliding model variable structure controller with auto-adjusted reaching law is researched in this paper.In the research,switch functions is taken as an error and reaching speed is adjusted by PID controller,with the intention of minimizing the traversing speed when arriving at the sliding model surface to reduce chattering and optimize the arrival time.According to the aero engine steady mathematic model,the sliding model variable structure control law is designed,the aero engine's sliding model controlle... |
