Capability to react to distributed noise. Comparison of the three controllers performed in terms of the RMSE during flexion extension sequence of 10 oscillations for a total duration of 100 s. Random noises of different amplitudes were added on the knee torque (ranging from 25% to 50% of the maximum knee torque values). The RMSE was evaluated separately for each oscillation of the angular trajectory (X axis), hence at different levels of fatigue.
