    • A controller, for force-controlling a drive source of a controlled object, having a position control circuit inside a force control circuit in order to define a relative position of the controlled object to a workpiece, and a contact force occurred between the workpiece and the controlled object, the controller including a first data acquiring portion for acquiring a time constant of the position control circuit based on a position command value to the drive source and an actual position value, during operations of the controlled object; a second data acquiring portion for acquiring a rigidity value for the controlled object and the workpiece based on a force data obtained when the controlled object is brought into contact with the workpiece; and an automatic gain calculating portion for calculating a force control gain of the force control circuit from the time constant of the position control circuit acquired by the first data acquiring portion and the rigidity value acquired by the second data acquiring portion, under conditions where a time constant of the force control circuit is larger than the time constant of the position control circuit.
    • 一种控制器,用于对控制对象的驱动源进行强制控制,在力控制电路内具有位置控制电路,以便限定受控对象与工件的相对位置,并且在工件和工件之间产生接触力 所述控制器包括第一数据获取部分,用于在所述受控对象的操作期间,基于对所述驱动源的位置指令值和实际位置值来获取所述位置控制电路的时间常数; 第二数据获取部分,用于基于当受控对象与工件接触时获得的力数据来获取受控对象和工件的刚度值; 以及自动增益计算部分,用于根据由第一数据获取部分获取的位置控制电路的时间常数和由第二数据获取部分获取的刚性值的时间常数来计算力控制电路的力控制增益, 力控制电路的常数大于位置控制电路的时间常数。
