In this paper, the trajectory tracking control problem with model predictive control approach is investigated for Unmanned Underwater Vehicle (UUV) control. Firstly, the kinematic tracking controller based on model predictive control (MPC) is applied to reach the tracking control in a kinematic way. Compared with conventional backstepping control, MPC can solve the speed jump control problem very...
Objectives. To investigate the relationship between intervertebral motion, intravertebral deformation and pain in chronic low-back pain patients.Design. This study measured vertebral motion of the lumbar spine and associated pain in a select group of chronic low-back pain patients as they performed a standard battery of motions in all planes.Background. Numerous studies have demonstrated that individuals...
