摘要
建立了从PWM逆变电源、电缆到电机的传动系统模型,考虑了振荡频率对电缆参数的影响。通过仿真电机端子上的PWM脉冲反射波瞬间电压,建立反射波峰值电压与上升时间和电缆长度之间的关系。本模型基于Matlab仿真软件下,允许改变上升时间、电缆长度、电机功率等参数,简单明确,仿真速度快,并经实验验证了仿真结果和模型的正确性。
The model of the drive system which includes PWM inverter, cable and induction motor is established, The influence of oscillation frequency on cable parameters is thought about. By imitating the trasienl voltage of the PWM reflect wave of the induction motor terminal the relations of reflect wave peak value with rise-time and cable length are established. This model is base on the Matlab imitation software. The parameters such as rise-time, cable length, motor power can be changed. The method is simple and explicit. It is also fast in imitation speed. The model correctness and imitation results are verified by examination.
