Development of multi-motor synchronous control system based on network-on-chip

Abstract

This article presents a novel system architecture based on network-on-chip for multi-motor synchronous control. The system integrates several servo motor controllers in a single chip which permits an increase to the number of motors according to the application requirements. Compared with traditional multi-motor control architectures, such as bus-based distributed architecture and single-core microprocessor architecture, network-on-chip-based architecture supports high-precision multi-axis real-time control with high network bandwidth and parallel processing. A four-wheel drive intelligent car experiment platform is developed for performance testing. It has a convenient process for parameter tuning. Several experiments are conducted to demonstrate the feasibility and real-time performances of the system. The research work has a good potential in integration, real-time performance of multi-motor synchronous control system.
