摘要:

在本文的范围内,机电和热力学模型推导出一系列的弹性致动器和开环和闭环转矩带宽参数分析考虑致动器的热力学行为。据观察,由于热力学限制,在整个扭矩参考幅度范围内,致动器的机电子系统的闭环扭矩带宽不可访问。因此,定子绕组温度估计为基础的自适应控制器的利用和分析,以提高控制器的基础转矩带宽的可访问性。本文实现了一个HEBI机器人X5-9驱动器作为案例研究的方法。

英文摘要:

Within the scope of the paper, electromechanical and thermodynamic models are derived for a series elastic actuator and open loop and closed loop torque bandwidth parameters are analysed considering the thermodynamic behaviour of the actuator. It was observed that the closed loop torque bandwidth of the electromechanical subsystem of the actuator was not accessible in the entire torque reference amplitude range due to thermodynamic limitations. Therefore, a stator winding temperature estimation based adaptive controller is utilised and analysed to improve the accessibility of the controller based torque bandwidth. This paper implements the methodology on a HEBI Robotics X5-9 actuator as a case study.
