A Learning Approach for Feed-Forward Friction Compensation
IFAC-PapersOnLine, 2018 An experimental comparison of two feed-forward based frictioncompensation methods is presented. The first method is based on theLuGre friction model, using identified friction model parameters, and ...

Pulsatile Physiological Control of Blood Pump-Cardiovascular System Based on Feedforward Compensation [PDF]
MicromachinesRotary Blood Pump (RBP) is a commonly used ventricular assist device. However, the constant speed operation of the blood pump leads to a reduction of blood flow pulsatility, which triggers a series of adverse reactions.

Pulse-Shaping Feed-Forward-Compensated Generator [PDF]
2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019 A typical electrical stimulator has a battery, step-up converter, voltage regulator, pulse generator with a micro-controller providing the clocking signal. This outputs a step response with a specified amplitude and pulse-width. In this work, Single-Ended Primary Inductance Converter (SEPIC) and Cuk converters are built to output a step response ...

Adaptive feed-forward hysteresis compensation for piezoelectric actuators [PDF]
Review of Scientific Instruments, 2012 Piezoelectric actuators are often employed for high-resolution positioning tasks. Hysteresis and creep nonlinearities inherent in such actuators deteriorate positioning accuracy. An online adaptive nonlinear hysteresis compensation scheme for the case of symmetric hysteretic responses and certain periodic reference trajectories is presented. The method

Exoskeleton transparency: feed-forward compensation vs. disturbance observer [PDF]
at - Automatisierungstechnik, 2018 Abstract Undesired forces during human-robot interaction limit training effectiveness with rehabilitation robots. Thus, avoiding such undesired forces by improved mechanics, sensorics, kinematics, and controllers are the way to increase exoskeleton transparency.
