    • This invention relates to a servo system for operating an exoskeleton adapted to encircle an object of interest and for supplying a force thereon. A servomotor is coupled to a power source and operates the position of the exoskeleton and thus the force exerted by the exoskeleton on the object of interest. A measuring unit measures a raw driving current signal I raw suplied by the power source to drive the servomotor. A low pass filter applies a low pass frequency filtering on the measured a filtered current signal I filtered. A processing unit determines an actuated current signal I actuated based on the servomotor setting parameters, where I actuated indicates the contribution to I raw from the servomotor when operating the position of the exoskeleton. The processing unit also determines a driving force current signal I force indication the force exerted by the exoskeleton on the object of interest, where I force is proportional to the difference between I filtered and I actuated.
    • 本发明涉及一种用于操作外骨骼的伺服系统,该外骨骼适于环绕感兴趣的物体并在其上提供力。 伺服电机连接到电源,并操作外骨骼的位置,从而控制外骨骼对感兴趣对象施加的力。 测量单元测量由电源供给的原始驱动电流信号I raw以驱动伺服电动机。 低通滤波器对经滤波的测量的经滤波的电流信号I进行低通滤波。 处理单元根据伺服电机设置参数确定启动的启动电流信号I,其中I启动表示当操作外骨骼的位置时来自伺服电机的I raw的贡献。 处理单元还确定驱动力电流信号I force,其指示由外骨骼施加在感兴趣对象上的力,其中I force与I过滤和I致动之间的差异成比例。
