Journal ArticleDOI
IMU-based joint angle measurement for gait analysis.
TL;DR: A set of new methods for joint angle calculation based on inertial measurement data in the context of human motion analysis are presented, including methods that use only gyroscopes and accelerometers and, therefore, do not rely on a homogeneous magnetic field.
Journal ArticleDOI
Voltage Stability and Reactive Power Sharing in Inverter-Based Microgrids With Consensus-Based Distributed Voltage Control
TL;DR: It is shown that the choice of the control parameters uniquely determines the corresponding equilibrium point of the closed-loop voltage and reactive power dynamics, and a necessary and sufficient condition for local exponential stability of that equilibrium point is given.
Proceedings ArticleDOI
Joint axis and position estimation from inertial measurement data by exploiting kinematic constraints
TL;DR: Novel methods for joint axis estimation and joint position estimation are presented that exploit the kinematic constraints induced by these two types of joints.
Journal ArticleDOI
Iterative learning control of a drop foot neuroprosthesis — Generating physiological foot motion in paretic gait by automatic feedback control
TL;DR: The results reveal that conventional trapezoidal stimulation intensity profiles may produce a safe foot lift, but often at the cost of too high intensities and an unphysiological foot pitch motion.
Journal ArticleDOI
Iterative Learning Control for Variable Pass Length Systems
TL;DR: In this paper, a necessary and sufficient monotonic convergence criterion for the 1-norm of the maximum pass length (MPL) error was found for linear iterative learning control (ILC) systems with changing pass length.
