Mode Switching Control (MSC) is a control method which switches from one control mode to another according to switching conditions. MSC has been widely used in robots and hard disk drives. Considering thrust limitations, however, the switching condition is generally conservative since there are not any clear criteria to switch the control modes. Therefore, this paper proposes a new index of switching...
In order to improve reliability and safety of an In-Wheel Motor, the Wireless In-Wheel Motor (W-IWM) using magnetic resonance coupling has been proposed. Transmitting power of the W-IWM is controlled by the primary inverter and the secondary converter. One of a technical issue of the W-IWM is transmitting power variation due to the load power variation and the coupling coefficient variation. In this...
Interior permanent magnet synchronous motors (IPMSMs) are employed for drive motors of electric and hybrid vehicles. Therefore, the control method in overmodulation range of inverter is important for fast torque response and expanding operation range of IPMSM. In this paper, the control methods based on perfect tracking control and PWM hold model are proposed in overmodulation range. The proposed...
