摘要/Abstract

摘要： 根据航空发动机在相似坐标系中特性不变的特点,提出一种基于相似理论的航空发动机转速自适应PID控制。该方案采用衰减曲线法进行换算PID参数整定,获得自适应调节律。仿真结果表明控制器具有良好的动静态性能,自适应性和鲁棒性。所得参数变化规律对数控系统全包线内PID控制器的参数选择具有一定的指导意义。

Abstract: Associated with the invariable characteristic of aeroengine on the similarity coordinate system, an adaptive PID speed control scheme based on similarity theory was proposed. The adaptive law was obtained from similarity PID parameters determined by the attenuation curve method. Simulation results show that controller has advantages of satisfactory performances, good adaptation and robustness. The adaptive PID parameters variation trend is useful for parameters selection of the aeroengine digital PID control system in full flight envelope.
