I. Introduction
Cooperative control of multimotor system is widely applied in industrial field that requires high synchronization and tracking accuracy among different motors, such as industrial manipulators and industrial robots. In these applications, the rapidity, traceability, and cooperativity of multimotor system play a key role in production efficiency and quality [1], [2]. Therefore, the current research of multimotor cooperative control is mainly focused on meeting the higher requirements for dynamic response, tracking accuracy, and synchronization performance to realize high-precision position control quickly and efficiently.
