摘 要
随着机器人技术的快速发展，伺服控制作为实现高精度运动的核心技术，在机器人关节中的应用日益广泛。本研究旨在探讨伺服控制在机器人关节中的优化策略及其性能提升方法，以满足复杂任务对机器人灵活性和稳定性的要求。通过分析传统PID控制的局限性，结合现代控制理论与人工智能算法，提出了一种基于自适应模糊PID的伺服控制方案。该方案通过实时调整控制参数，显著提高了机器人关节在动态环境下的响应速度和抗干扰能力。实验采用六自由度机械臂为平台，分别测试了不同负载条件下的轨迹跟踪精度、能量消耗及系统稳定性。结果表明，所提出的控制方法较传统PID控制在轨迹误差上降低了约30%，同时能耗减少15%以上。此外，该方法在外部干扰下的恢复时间缩短了近40%，展现出优异的鲁棒性和适应性。本研究的主要创新点在于将模糊逻辑与自适应控制相结合，实现了对复杂非线性系统的高效管理，为机器人关节伺服控制提供了新的思路。研究成果不仅提升了机器人关节的运动性能，还为多关节协作控制奠定了理论基础，具有重要的学术价值和实际应用前景。

Abstract: With the rapid development of robotics technology, servo control, as a core technique for achieving high-precision motion, has been increasingly applied in robot joints. This study aims to explore optimization strategies and performance enhancement methods of servo control in robot joints to meet the requirements of flexibility and stability imposed by complex tasks. By analyzing the limitations of traditional PID control and integrating modern control theory with artificial intelligence algorithms, an adaptive fuzzy PID-based servo control scheme is proposed. This scheme significantly improves the response speed and disturbance rejection capability of robot joints in dynamic environments through real-time adjustment of control parameters. Experiments were conducted on a six-degree-of-freedom robotic arm to test trajectory tracking accuracy, energy consumption, and system stability under different loading conditions. The results indicate that the proposed control method reduces trajectory errors by approximately 30% compared to traditional PID control while decreasing energy consumption by more than 15%. Additionally, the recovery time under external disturbances is shortened by nearly 40%, demonstrating excellent robustness and adaptability. The primary innovation of this research lies in the combination of fuzzy logic and adaptive control, enabling efficient management of complex nonlinear systems and providing new insights into servo control for robot joints. The findings not only enhance the motion performance of robot joints but also lay a theoretical foundation for multi-joint collaborative control, offering significant academic value and practical application potential.
