Manufacturing and Control of a Robotic Device for Time-averaged Simulated Micro and Partial Gravity of a Cell Culture Environment
International Journal of Control, Automation and Systems - Tập 18 - Trang 53-64 - 2019
Yoon Jae Kim, Min Hyuk Lim, Byoungjun Jeon, Dong Hyun Choi, Haeri Lee, Ae Jin Jeong, Min Jung Kim, Ji Won Park, Ja-Lok Ku, Seung-Yong Jeong, Sang-Kyu Ye, Youdan Kim, Sungwan Kim
Gravity is omnipresent for all objects on Earth. However, in an environment of different gravitational stress (e.g., microgravity or partial gravity), cells and organs show different biological responses. So, researchers have attempted to achieve micro- or partial gravity on Earth through various approaches, such as parabolic flight or free fall. However, the duration of such ground experiments is...... hiện toàn bộ

Direct power control of grid connected voltage source inverters using port-controlled Hamiltonian system
International Journal of Control, Automation and Systems - Tập 15 - Trang 2053-2062 - 2017
Yonghao Gui, Gil Ha Lee, Chunghun Kim, Chung Choo Chung
This paper presents a new direct active and reactive power control (DPC) scheme for a three-phase grid connected voltage source inverter (VSI) based on the passivity viewpoint using the port-controlled Hamiltonian (PCH) system. The proposed controller consists of feedforward and feedback parts. The feedforward part (the reference inputs) is generated through the flatness of the dynamics of the VSI...... hiện toàn bộ
Exponential H ∞ control for singular systems with time-varying delay
International Journal of Control, Automation and Systems - Tập 15 - Trang 1592-1599 - 2017
Jiemei Zhao, Zhonghui Hu
This paper studies the exponential admissibility and H ∞ control problems for a class of singular systems with time-varying delay in state. Firstly, an exponential admissibility criterion is obtained based on linear matrix inequalities (LMIs). It is worth mentioning that the derivative of the time-varying delay does not need to be smaller than one. Based on the prop...... hiện toàn bộ
Robust Multiple Fault Isolation Based on Partial-orthogonality Criteria
International Journal of Control, Automation and Systems - Tập 20 - Trang 2148-2158 - 2022
Nicholas Cartocci, Francesco Crocetti, Gabriele Costante, Paolo Valigi, Mario L. Fravolini
In this paper, a data-driven scheme for the robust Fault Isolation of multiple sensor faults is proposed. Robustness to modelling uncertainty and noise is achieved via the optimized design of the processing blocks. The main idea of the study is the introduction of a Pre-Isolation block that selects a restricted set of sensors containing (with high probability) the subset of the faulty sensors; in ...... hiện toàn bộ
Unknown Input Observer Design for Takagi-Sugeno Systems with Fuzzy Output Equation
International Journal of Control, Automation and Systems - Tập 17 - Trang 267-272 - 2019
Jitao Li, Zhenhua Wang, Yi Shen, Yipeng Liu
This paper studies unknown input observer design for discrete-time Takagi-Sugeno fuzzy systems. The proposed unknown input observer has a new structure that can be applied to Takagi-Sugeno fuzzy systems with nonlinear output equation. We derive the design conditions of the proposed unknown input observer based on Lyapunov function and convert them into a set of linear matrix inequalities. Numerica...... hiện toàn bộ
Improved Function Augmented Sliding Mode Control of Uncertain Nonlinear Systems with Preassigned Settling Time
International Journal of Control, Automation and Systems - - 2020
Guangbin Cai, Xinyu Li, Mingzhe Hou, Guangren Duan, Fei Han
This paper investigates the robust tracking control of second-order uncertain nonlinear systems by adopting the function augmented sliding mode control approach. An improved version of this approach is proposed such that the exact information of the initial tracking error is not required when generating the desired trajectory of the tracking error. This evidently enlarges the application scope of ...... hiện toàn bộ
Neurogenic bladder dysfunction: a novel treatment using robust model predictive control supported by noise attenuation technique
International Journal of Control, Automation and Systems - Tập 15 - Trang 2669-2680 - 2017
Hesham W. Gomma, Jean Thomas
Neurogenic bladder is one of the known diseases that affects the Lower Urinary Tract (LUT) leading to a dysfunctional operating pattern. The disease is mainly attributed to disorders in the central nervous system or peripheral nerves which play the major role in controlling the micturition process. This paper suggests a new technique to treat this disease considering robust Model Predictive Contro...... hiện toàn bộ
Semi-automatic Knob System for Assisting Flexible Endoscope Steering
International Journal of Control, Automation and Systems - Tập 18 - Trang 2650-2657 - 2020
Hyun-Soo Yoon, Byung-Ju Yi
In this paper, a semi-automatic knob system for assisting control of flexible endoscope is introduced. For conventional flexible endoscope, the torque to bend the bending part is increased proportionally to the curvature of the insertion tube. As the bending angle increases, the required torque is increased. This characteristic makes a surgeon tired. The proposed semi-automatic knob system consist...... hiện toàn bộ
