Due to the motion disturbances in the environment (currents), these tasks are important to keep the vehicle stabilized relative to an external reference frame.
Our results, using serial long term ECG, QRS duration, and corrected QT interval, show no evidence of ventricular wall motion disturbances, left ventricle hypertrophy, valve dysfunction, fibrosis, or pericardial effusion at 4 weeks following transplantation of autogeneic mitochondria [19].
My friend was determined to see into its walled back garden, so we walked down an alley, ascended a metal staircase on the side of a church, climbed on top of the stairs' highest railing — and from there we could see down into it: Miss Havisham's garden, the Eden of the 19th-century novel, source of all desire, conflict, motion, disturbance and growth.
The tracking performance of the EHLS is mainly limited by the actuator's motion disturbance, flow nonlinearity, and friction, etc.
In the (psi >pi /2) and (psi <-pi /2) regions, the effect can be understood as a <span class="lh">motion disturbance through Eqs.
The tracking performance of EHLS is mainly affected by the following factors: actuator's active motion disturbance, flow nonlinear and parametric uncertainties, etc.
Most previous studies on EHLS pay too much attention on actuator's active motion disturbance, while deemphasize the other two factors.
Besides actuator's motion disturbance, both the nonlinear characteristics and parametric uncertainties of the loading system are addressed by the present controller.
Besides actuator׳s motion disturbance, both the nonlinearity characteristics and friction problem of the EHLS system are taken into consideration in this paper.
In order to suppress actuator׳s motion disturbance, a nonlinear robust dual-loop control scheme is developed, which consists of a open-loop nonlinear velocity feed-forward compensator and a closed-loop nonlinear deterministic robust torque controller.
The main function of the open-loop compensator is to decouple actuator׳s active motion disturbance, whereas the torque loop controller aims at guaranteeing the dynamics performance of tracking torque reference.
