    摘要:

    针对下肢助力外骨骼膝关节位置伺服系统运动过程中伺服精度要求高、冲击力矩大、负载变化范围广等特点,提出了一种运用模糊规则调节的位置伺服系统滑模控制策略.该策略设计了一种新型带有积分项的滑模面模糊调节部分的结构为单输入双输出,选用模糊规则调节新型终端滑模型趋近率来抑制滑模抖振.仿真及实验表明,该控制策略稳定性和伺服跟踪性好,对负载干扰的鲁棒性强.

    Abstract:

    Aiming at characteristics of the lower limb assisted exoskeleton knee joint position servo systems, such as high servo accuracy, large impact torque and wide load range, a sliding mode control strategy of position servo system based on fuzzy rules is proposed. This strategy designs a new type of sliding mode surface with integral terms. The structure of the fuzzy adjustment part is of single input and double output. Fuzzy rules are used to adjust the new terminal sliding mode approach rate to suppress sliding mode chattering. Both experiments and simulations demonstrate that the control strategy has good stability and servo tracking performances, and strong robustness with respect to load disturbances.
