The system selects the STM32G473 microcontroller as the control chip and adopts field-oriented control as the primary motor control algorithm. Meanwhile, the drive and control system design is completed from both hardware and software aspects. Finally, the study performs closed-loop experiments on the robotic arm joint. The experimental results demonstrate that the designed drive and control system for robotic arm joints exhibits a favorable dynamic response and steady-state performance, making it suitable for controlling desktop-level and lightweight robotic arms.
