如今，气动执行器在工业中得到了广泛的应用，气动控制器的类型也多种多样。然而，很少有文章讨论气动马达的动力学和控制器的性能。本文旨在分析气动马达的动力学并设计合适的速度控制器。本研究中的气动马达的速度由电动控制阀控制，以调节进气的压力和流量。研究中通过阶跃响应来确定系统的参数。实验结果发现，气动马达的死区相当显着，会影响整个系统的性能。因此，在设计速度控制器时必须仔细分析摩擦力和入口压力的影响
Nowadays, air actuators are widely used in industry with different many types of pneumatic controllers. However, few articles discussed the dynamics of air motors and performance of controllers. This paper intends to analyze the dynamics of air motors and design suitable speed controllers. The speed of an air motor in this research is controlled by an electrical control valve for adjusting the pressure and flow rate of inlet air. The parameters of the system are identified through step responses in the research. It is found from experiment results that the dead-zone of an air motor is quite significant and will affect the overall system performance. Hence, the effect of friction and inlet pressure must be carefully analyzed when designing the speed controller
