[0040] Concrete steps of the inventive method:
[0041] Step 1. The main circuit of the electric vehicle drive motor is generally powered by a three-phase bridge voltage source inverter U1, and the power supply is a DC power supply U10. Since the power device of the inverter is not an ideal switching device, its tube voltage drop has a great influence on the nonlinear output phase voltage and phase current of the inverter. figure 1 Shown is the characteristic curve of EUPEC's power device BSM50GB120DN2 and the saturation voltage drop curve of the diode. After linearization as figure 1 Shown by the dotted line in , that is, the conduction voltage drop of the power device u ce Approximately regarded as a fixed threshold voltage u th Combination of its impedance voltage drop.
[0042] Step 2: The PC U5 sets the rotational speed signal, and drives the motor of the electric vehicle to rotate by changing the set rotational speed. The speed sensor U9 is sampled by the encode...
