为提高柔性机器人的运动性能,设计了一种基于弧形螺旋弹簧的旋转型串联弹性驱动器,采用多级回转轴承组合结构,将刚度不同的弹簧内外双层串联,实现关节的大范围柔性输出。建立弹性驱动器动力学模型,采用反演控制方法,设计了弹性驱动器柔性关节控制器;采用Matlab和Adams软件进行联合仿真,对外力干扰下柔性关节的动力学性能进行了仿真分析。结果表明,控制器能够克服干扰力使柔性关节在0.59 s内恢复平衡状态,验证了所设计弹性驱动器结构和控制规律的有效性。
In order to improve the motion performance of compliant robots
a rotary series elastic actuator (SEA) based on arc helical springs is designed. The proposed SEA can be used to provide a wide range of flexible torsion by the combination of multi-stage rotary structures. The inner and outer double layers of springs with different stiffness are connected in series. The dynamic model of the flexible joint with the proposed SEA is established. The control law for the flexible joint is derived by the backstepping algorithm. To validate the effectiveness of the proposed SEA and the control law
the dynamic performance of the flexible joint with interference torques is simulated by Matlab and Adams. The results show that the controller can overcome the interference force and restore the balance state of the flexible joint within 0.59 s,which verifies the effectiveness of the designed elastic actuator structure and control law.
