Abstract: In response to the difficulty in meeting the real-time control requirements of mechatronics systems in high dynamic environments, this study aims to explore an efficient solution to improve system response speed and control accuracy. Taking the industrial welding robotic arm project as an example, by analyzing the shortcomings of traditional control systems in terms of calculation speed and response delay, a real-time control system architecture based on FPGA was designed and implemented. The implementation process of parallel computing and algorithm optimization was emphasized, and innovative optimization measures for inverse kinematics solution and multi axis coordinated control were proposed. The research results show that the system exhibits significant advantages in control cycle, position accuracy, and trajectory tracking, addressing the high real-time requirements in complex task scenarios.
