| Outline of Research at the Start |
A novel pulse-amplitude modulation control with a fuzzy-based automatic excitation angle scheme and adaptive deadtime algorithm is proposed and useful, that is assessed to reduce the interior permanent magnet synchronous motor core, copper and inverter losses in experiments and simulation.
Moreover, a detailed analytical model with the mutual consideration of effects of key components in the motor system and physical insights is studied to verify the measured results.
The proposed control can be effectively applied for direct motor drives or synchronous in-wheel motors used in electric vehicles.

| Outline of Annual Research Achievements |
- A novel pulse amplitude modulation (PAM) control with a fuzzy-based automatic excitation angle scheme was successfully developed and implemented in an experimental IPMSM drive under silicon carbide (SiC) inverter excitation at different rotational speeds. Furthermore, I successfully developed an adaptive dead-time algorithm for the IPMSM drive under inverter excitation.
- In addition, the IPMSM core loss, copper loss, voltage-current harmonics, and inverter loss were thoroughly evaluated. Besides, the mutual effects of the dead-time and control sample time at high switching frequencies on the motor core loss and inverter loss were measured and assessed. Physic-based insights and explanations of the obtained results were also provided and discussed in detail.
- Moreover, an isolated two-phase buck-boost converter was successfully researched and implemented for improvement of DC-bus voltage control in motor drive systems. Other measured results with a gallium nitride (GaN)-based IPMSM drive and ring test were additionally evaluated. For further evaluation, simulation models in MATLAB and JMAG software were also designed for numerical analysis on the core loss and harmonics of the IPMSM under the proposed PAM control and adaptive dead-time scheme.
- In addition to many relevant publications presented in FY2023, another research manuscript was submitted to prestigious journal and other two research manuscripts were submitted to IEEE-sponsored international conferences. These three related manuscripts are currently under review and will be probably published by 31 December 2024.
