Trunk Angle Modulates Feedforward and Feedback Control during Single-Limb Squatting
Journal of Functional Morphology and Kinesiology, 2021 Trunk positioning and unexpected perturbations are high-risk conditions at the time of anterior cruciate ligament injury. The influence of trunk positioning on motor control responses to perturbation during dynamic performance is not known. We tested the

A flow disturbance estimation and rejection strategy for multirotors with round-trip trajectories [PDF]
, 2020 This paper presents a round-trip strategy of multirotors subject to unknown flow disturbances. During the outbound flight, the vehicle immediately utilizes the wind disturbance estimations in feedback control, as an attempt to reduce the tracking error ...

Dynamic Effect of Input-Voltage Feedforward in Three-Phase Grid-Forming Inverters
Energies, 2020 Grid-connected and grid-forming inverters play essential roles in the utilization of renewable energy. One problem of such a converter system is the voltage deviations in the DC-link between the source and the inverter that can disrupt the inverter ...

Training Reflexes Using Adaptive Feedforward Control
IEEE Open Journal of Control Systems, 2023 We consider the problem of mixed feedforward and feedback based disturbance rejection, where the feedforward measurement only provides a partial reconstruction of the disturbance.

Direct data-driven control approach of reference shaping for two degree of freedom control
SICE Journal of Control, Measurement, and System Integration, 2022 In this study, we propose a novel data-driven approach for control of two degrees of freedom systems. The proposed method uses one-shot experimental data to derive the reference governor for improving control performance.

Linear motor motion control using a learning feedforward controller [PDF]
, 1997 The design and realization of an online learning motion controller for a linear motor is presented, and its usefulness is evaluated. The controller consists of two components: (1) a model-based feedback component, and (2) a learning feedforward component.
