Therefore the PD control law with compensation satisfies the motion control objective globally. This implies in particular that for any initial position error ặ 0 e IR and any velocity error ặ 0 e IR we have IÍIII -x ặ í 0. For any choice of the symmetric positive definite matrices Kp and Kv the origin of the closed-loop equation of a robot with the PD control law r7 zT t expressed in terms of the state vector q q is globally uniformly asymptotically stable. Therefore. PD ehntrol satisfies the metier control objective globally. In particular for any initial position error ặ 0 e IR and velocity error ặ 0 e IR we have lrnit- 00 q t 0.
