摘要

The integration of closed-loop control systems in hybrid stepper motors has been recognized as a significant advancement in enhancing the precision and reliability of robotics applications. Hybrid stepper motors, known for their high resolution, are extensively utilized in precision robotics due to their capability to perform accurate positioning tasks. However, limitations inherent in traditional open-loop control systems, such as overshoot, oscillations, and the potential loss of steps, often lead to permanent errors and diminished system performance. To address these challenges, a closed-loop control (CLC) system has been implemented, which incorporates feedback sensors that continuously monitor the motor’s position and speed. Real-time adjustments are enabled through this feedback, allowing for the mitigation of errors and the enhancement of system stability. As a result, overshoot and settling time are significantly reduced, ensuring that the motor operates within the desired parameters. This approach has been shown to improve accuracy, making it particularly suitable for applications where exact positioning and consistent speed control are critical. The performance of the closed-loop (CL) system was analyzed and compared to traditional systems, with results indicating a superior ability to maintain precision under varying operational conditions. The importance of CL feedback in achieving high-performance outcomes in robotics is highlighted, providing valuable insights into the development of advanced control systems for hybrid stepper motors and paving the way for efficient robotic systems.
