“…With the flourishing development of industry and the gradual improvement of productivity, the application of PMSM is not limited to a single main control system of a single motor, but it extends to the real-time control of multiple motors simultaneously [22], such as mechanical phased array antenna, multi-joint manipulator, multi-axis linkage CNC machine tools, and other application scenarios. In these scenarios, some motor drive systems should control multiple motors in the system synchronously or asynchronously through a single main control chip [23], which requires the superior performance of the motor control system [24]. In recent years, many researchers have devoted themselves to improving the efficiency of multi-axis servo control systems.…”

The multi-axis servo control system has been extensively used in industrial control. However, the applications of traditional MCU and DSP chips in high-performance multi-axis servo control systems are becoming increasingly difficult due to their lack of computing power. Although FPGA chips can meet the computing power requirements of high-performance multi-axis servo control systems, their versatility is insufficient, and the chip is too costly for large-scale use. Therefore, when designing the universal SoC, it is better to directly embed the coprocessor IP core dedicated to accelerating the multi-motor vector control current loop operation into the universal SoC. In this study, a coprocessor IP core that can be flexibly embedded in a universal SoC was designed. The IP core based on time division multiplexing (TDM) technology could accelerate the multi-motor vector control current loop operation according to the hardware–software coordination scheme proposed in this study. The IP was first integrated into a universal SoC to verify its performance, and then the FPGA prototype verification for the SoC was performed under three-axis servo control systems. Secondly, the ASIC implementation of the IP was also conducted based on the CSMC 90 nm process library. The experimental results revealed that the IP had a small area and low power consumption and was suitable for application in universal SoC. Therefore, the cheap and low-power single universal SoC with the coprocessor IP can be suitable for multi-axis servo control.
