Background：
The coordination strategy of existing distributed drive systems primarily emphasizes torque allocation by upper-level controllers, often neglecting the performance indicators of each in-wheel motor and the coordination among motor controllers. Furthermore, the redundancy of multi-motor controllers and multi-actuators in distributed drive systems results in low fault tolerance for signal transmission.

Contributions：
- Proposed the integrated modulation control concept, which reduces the complexity of the underlying controller architecture and serves as a framework for further algorithms to achieve high dynamic performance for individual motor drives while facilitating rapid coordination among multiple motors.
- Proposed an integrated direct torque control strategy that utilizes multiple voltage vector modulation for a distributed multiple in-wheel motor drive system, grounded in integrated modulation control concept.
- Developed and analyzed frequency ratio integrated modulation and virtual vector integrated modulation methodologies based on multiple voltage vector modulation principle.
- Invented a multiple in-wheel motor integrated modulation drive system, incorporating a vehicle controller, multi-mode secondary devices, and integrated drivers.
Achievements:
- Paper has been published in IEEE Transactions on Industrial Electronics (Early Access).
- Chinese Invention Patent Application accepted (Publication Date: 12-Nov-2024).
