“…Different from control paradigms that do not consider human inputs, the proposed approach requires the information of volitional human motion to compute control laws u d and u. Therefore, we modify an existing model-based NDO [22] to estimate human joint torques using only angular information [30]. Let B λ = B − A T λ, τhum = (I − A T λ)τ hum , and define z = M −1 (τ hum + J T F perturb ) as the term to be estimated, left-multiplying M −1 at both sides of (1), we have…”
