Damping and transfer control of spherical pendulum with omni-directional mobile robot

Nihon Kikai Gakkai ronbunshu, 2015
This paper presents damping and transfer control with an omni-directional mobile robot. The robot moves in all directions by using three omni-wheels, and a spherical pendulum was used as the tentative transfer object.

Reference-Feedforward Power-Synchronization Control [PDF]

IEEE Transactions on Power Electronics, 2020
In this letter, an enhancement of power-synchronization control is proposed, whereby pole–zero cancellation in the closed-loop system is achieved. An effect thereof is that step-response ringing and overshoot are eliminated. For strong grids, the closed-loop bandwidth increases, allowing a shorter step-response rise time.

Continual Learning for Multimodal Data Fusion of a Soft Gripper

Advanced Robotics Research, EarlyView.
Models trained on a single data modality often struggle to generalize when exposed to a different modality. This work introduces a continual learning algorithm capable of incrementally learning different data modalities by leveraging both class‐incremental and domain‐incremental learning scenarios in an artificial environment where labeled data is ...

Feed size distribution feedforward control for a grinding mill circuit [PDF]

, 2019
This paper proposes a method to measure and reject disturbances caused by changes in the ore distribution of the feed to a grinding mill circuit. A computer vision system is presented to measure the fraction of rocks in the feed, using only basic ...

A State‐Adaptive Koopman Control Framework for Real‐Time Deformable Tool Manipulation in Robotic Environmental Swabbing

Advanced Robotics Research, EarlyView.
This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

Efficient and Robust Standing Postures of Quadruped Robots

Advanced Robotics Research, EarlyView.
A calibrated static framework estimates load, optimizes torques, and adapts posture so quadruped robots stand efficiently and robustly under external payloads, achieving up to 50% lower torque demand. Inspired by the natural posture adjustments of animals under external loading, this article presents an optimization‐based framework for minimizing joint

An Iterative Tuning Method for Feedforward Control of Parallel Manipulators Considering Nonlinear Dynamics

Chinese Journal of Mechanical Engineering
Feedforward control is one of the most effective control techniques to increase the robot’s tracking accuracy. However, most of the dynamic models used in the feedforward controllers are linearly simplified such that the nonlinear and time-varying ...

Rational iterative feedforward tuning: Approaches, stable inversion, and experimental comparison

, 2016
Feedforward control plays a key role in achieving high performance for industrial motion systems that perform non-repeating motion tasks. Recently, learning techniques have been proposed to further improve both performance and robustness to non-repeating
