Abstract(E) | In recent years, the movement toward a decarbonized society has accelerated worldwide, and electrification is also progressing in the automobile industry. But in general, xEVs are more expensive than ICE vehicles due to the complexity of the system and soaring raw material prices, so there is a need to reduce the cost of electric powertrains. In the field of motor control, a method called vector control has been developed in order to achieve higher performance, and these have required current sensors and position sensors. Therefore, to simplify these systems, many sensor less control technologies that substitute sensor functions using various estimation methods are being studied, by eliminating sensors. The generator motor for 100% electric drive hybrid vehicles need to quickly reach the engine ignition rotation speed when power generation is requested, so a fast rotation speed change is required. However, there are issues that the possible torque when the rotation speed changes quickly is lower than it when the rotation speed is constant and that smooth estimation method switching cannot be performed when the estimation method is gradually switched. This paper shows the effects of the correction of the phase error estimated value in consideration of the rotation change speed and the correction of the phase error estimated value by the deviation between the final phase estimated value and the phase estimated value of each estimation method. Furthermore, in the bench evaluation as a generator motor for 100% electric drive hybrid vehicle, it was confirmed that the torque and rotation speed changes required by the system can be achieved with position sensor less drive. |
