摘　　要：为了实现舰载轻型天线稳定平台的高精度控制,直流电动机机电时间常数Tm和电气时间常数Tl的准确测量在伺服控制系统设计中具有十分重要的指导意义。在考虑摩擦力矩的情况下,导出了如何运用启动电流法测取直流电动机机电时间常数Tm和电气时间常数Tl的测试计算方法,并设计了该系统的双闭环系统调节器。结果表明,该系统具有较高的响应速度、较高的稳定精度和较强的抗负载扰动能力,具有很强的鲁棒性和自适应能力。In order to realize high precision control of stable platform of light antenna,it is very important that whether exact measuring of electromechanical time constant and electric time constant for DC brushless motor is correct or not.This paper introduce how to measure the electromechanical time constant and electric time constant using the method of initial current measurement in the case of friction moment.A project design method of the double closed loop control system is designed.It shows that the system possesses high accurate and steady precision,strong anti-jamming,high robustness and self-adaptability.
