无刷直流电机控制技术在呼吸机上的应用

Application of BLDC motor in CPAP Machines

首先从理论上介绍了呼吸机系统的物理模型,并简要地分析了系统实现稳定控制的原理,然后提出了采用PI控制的策略。其次,详细地介绍了呼吸机系统的软、硬件实现方式和实现过程,最后通过实验数据说明控制的稳定性。

Firstly, the model of CPAP system is introduced in theory while the principle of stabilization control is briefly analyzed, and then, the scheme of PI control is put forward. Secondly, the hardware and software implementation of the CPAP system and the process of the system are introduced in detail. Finally, the stability of the control is illustrated by experimental data.
