Reducing Disturbances Caused by Reductions in Regenerative Brake Torque

SAE Technical Paper Series, 2011
<div class="section abstract"><div class="htmlview paragraph">This paper presents a method to reduce the number of occurrences of vehicle deceleration disturbances due to the reduction of regenerative braking in the presence of wheel slip. Usually, regenerative braking is disabled when wheel slip is detected in order to allow the ABS system

Real-time path tracking with torque limits by using a disturbance observer

Proceedings of the 1994 IEEE International Conference on Robotics and Automation, 2002
When the minimum-time trajectory of a manipulator along a geometrically prescribed path is planned, considering the manipulator's dynamics and actuators' torque limits, at least one of the joints is at the torque limit. The execution of such a trajectory by a conventional feedback scheme results in torque saturation.

Switching Position-Torque Control for Series Elastic Actuators with Disturbance Observer

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper proposes a novel switch control for the series elastic actuator (SEA). This switch control provides more robust position control along with better impulse dissipation performance. SEA is an actuator technology commonly used in robotic applications that require safe and precise interaction control.

Transient damping torques in synchronous machines during disturbances

Proceedings of the Institution of Electrical Engineers, 1969
During power-system disturbances, the relative speed between the resultant flux and the rotor causes eddy currents to be induced in the rotor iron structure and an induction-motor or induction-generator torque to be developed owing to the amortisseur winding; both these effects damp out the synchronousmachine oscillations.

Drive induced torque disturbances in brushless rate servos

Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting, 2002
The torque disturbances caused by imperfections in a permanent magnet brushless sinusoidal motor and sinusoidal power amplifier are discussed, and the major sources of disturbances are quantified. Brushless rate servos are shown to contain many new sources of torque disturbances, in addition to the disturbances produced by brush type rate servos.

Analysis of estimation error of observer for disturbance torque and velocity

Electrical Engineering in Japan, 1994
AbstractThis paper analyzes some features of estimation error of the observer which estimates disturbance torque and velocity. This observer inputs the information of driving torque and current position, and outputs the information of disturbance torque and velocity.Although this observer is a practical tool to compose a robust control system, there ...
