Parameters “True” Values
K11 (Nm/rad) 891.07
B11 (Nm/(rad/s)) 151.48
K21 (Nm/rad) 286.42
B21 (Nm/(rad/s)) 19.09
Kpas1 (Nm/rad) 152.76
Td1 (ms) 90
K22 (Nm/rad) 175.03
B22 (Nm/(rad/s)) 28.00
K12 (Nm/rad) 251.41
B12 (Nm/(rad/s)) 50.70
Kpas2 (Nm/rad) 19.09
Td2 (ms) 80
m1, m2 (kg) 20.7, 48
J1, J2 (kg m2) 0.955, 2.73
h1, h2 (m) 0.521, 0.301
L1 (m) 0.826

Note: m1 and m2 are mass of lower body (LB) and upper body (UB) segments, respectively. h1 and h2 are center of mass height above the ankle and hip, respectively. J1 and J2 are moments of inertia about center of mass for LB and UB segments, respectively. L1 is the length of the LB segment. For comparison, Engelhart et al. (2015) reports inertia values about inferior end of segments. Control parameters are similar to those reported in Boonstra et al. (2013) and Engelhart et al. (2015).
