摘要
本文介绍和分析了电子气动式座舱压力控制系统各部件的结构特性,建立了座舱、控制器、力矩马达、控制腔及排气活门等部件的数学模型,并将非线性部分进行了线性化处理;获得控制系统的传递函数。然后根据系统的稳定性判据确定PID参数的基本取值范围,最后通过Matlab软件仿真进一步获得系统某平衡状态下动态性能较好时的PID参数值。
Electronic-pneumatic cabin pressure controlling system was introduced and analyzed in the paper. The mathematical models were established which included the aircraft cabin, controller, motor, controlling cavity and outflow valve etc. The transfer function was obtained by liberalizing mathematical models of the controlling system. The steady state of the system were analyzed and the range of PID(Proportional Integral Derivative) parameters were obtained. Lastly, the preferable parameters is obtained by the d...
