Hi, may I ask what exactly is "Model-based Impedance Tuning control"?

MIT (Model-based Impedance Tuning) control for joints (CAN ID: 0x15A-0x15F)

Does it correspond to the following equation?

$$c_{ref} = Kp * (p_{des} - θ_m) + Kd * (v_{des} - dθ_m) + c_{ff}$$

  • $c_{ff}$ feedforward current
  • $c_{ref}$ reference current
  • $p_{des}$ is the expected position of the motor side, in counts;
  • $θ_m$ is the current position of the motor side, in counts;
  • $v_{des}$ is the expected speed of the motor side, in rpm;
  • $dθ_m$ is the current speed of the motor side, in rpm;
