Block diagram representation of the three-levels control system. The high-level control distinguishes the activity. The mid-level control modulates the reference torque Inline graphic required for the specific activity identified. The low-level control regulates the actuators output Inline graphic . The exoskeleton Inline graphic (as an admittance) and the human Inline graphic (as an impedance) are mechanically interconnected.
