本课题是利用单片机作为核心器件研制的一套可应用于现场的动平衡测试系统。该系统能完成现场动平衡单面或双面测试，实时给出不平衡量的大小和相位。也可单独测转速和振动，还能对采集到的振动信号作时域、频域图显示。 - In the design of real - time control system , the paper takes three - phase full - bridge mosfet inverter as the real - time control main circuit , and adopts a control scheme with 120 ? switching mode combined with half - bridge pulse width modulation ( pwm ) , which would avoid straightthrough short of a certain bridge . phase current is detected by single current sensor ; three - phase position signals generated by position sensors could not only supply commutation information for inverter , but also be used for speed detecting based on signals " period measurement , which makes the speed sensor unnecessary . the whole control system adopts speed and current dual closed - loop control strategy in order to construct a high performance rare - earth permanent magnetic brushless dc motor ( repm bldcm ) full - digital real - time control system
在实时控制系统的设计中，本文以三相全桥mosfet逆变电路作为实时控制主电路，采用120导通方式结合半桥pwm调制的控制方案，从而有效地避免了桥臂的直通短路；本文用单电流传感器实现对相电流的检测，来自位置传感器的三相位置信号不仅为逆变电路提供换相信息，而且也用于基于信号周期测量的转速检测，这样就省去了速度传感器；系统采用的是速度、电流双闭环控制策略，力求构建高性能的稀土永磁无刷直流电动机全数字实时控制系统。
