  • Publication number: 20220134542
    Abstract: A position/force controller performs a first conversion for distributing control energy to at least one of velocity or position energy and force energy, in accordance with a function to be realized, based on velocity (or position) and force information, which correspond to information relating to a position based on an operation of an actuator, and information serving as reference of control. The position/force controller calculates at least one of a velocity or position control amount and a force control amount based on at least one of the energies obtained through the distribution. The position/force controller integrates the calculated control amounts, performs a second conversion, and determines input to the actuator. The position/force controller performs a process, corresponding to increasing or decreasing performed on at least one of the velocity or position energy and the force energy together or independently, with satisfaction of a condition set for the control energy.
