Verify the properties of skew symmetry, passivity and linearity in the parameters for the system given by Equation (9.6). Compute bounds on the inertia matrix, M(q), in terms of bounds on D(q). Show that M(g) is positive definite.
9-1 Verify the properties of skew symmetry, passivity and linearity in the parameters for the system given by Equation (9.6). Compute bounds on the inertia matrix, M(q), in terms of bounds on D(q). Show that M(q) is positive definite.
for k=1,…,n, where Bk?=Bmk??+Kbk??Kmk??/Rk?. Multiplying Equation (9.2) by the gear ratio rk? and using the fact that the motor angles ?mk?? and the link angles qk? are related by ?mk??=rk?qk? we may write Equation (9.2) as rk2?Jm?q¨?k?+rk2?Bk?q??k?=rk?Kmk??/RVk???k? Substituting Equation (9.4) into Equation (9.1) yields rk2?Jmk??q¨?k?+?j=1n?dkj?q¨?j?+?i,j=1n?cijk?q??i?q??j?+rk2?Bk?q??k?+gk?=rk?RKm??Vk? for k=1,…,n. In matrix form Equation (9.5) can be written as M(q)q¨?+C(q,q??)q??+Bq??+g(q)=u
