Development of constrained control allocation for ship berthing by using autonomous tugboatsInternational Journal of Control, Automation and Systems - Tập 9 - Trang 1203-1208 - 2011
Phuoc Van Bui, Young Bok Kim
In this paper, we propose a new approach to ship berthing by using autonomous tugboats. This approach overcomes the nominal effectiveness problem of actuators at slow speed maneuvering to improve the ship operation in the harbor area. The proposed SMC gave us a sliding mode control law that guarantees position tracking with desired velocity in the presence of environmental disturbances. The thrust...... hiện toàn bộ
A Proactive Nonlinear Disturbance Compensator for the Quarter CarInternational Journal of Control, Automation and Systems - Tập 18 - Trang 2012-2026 - 2020
Johannes N. Strohm, Dominik Pech, Boris Lohmann
A new Proactive Nonlinear Disturbance Compensator (PNDC) for vibration damping in a quarter car is presented. A Flatness Based Disturbance Compensator (FBDC) for a nonlinear quarter car model is derived that decouples the chassis acceleration completely from the known road disturbance. This leads to a high level of driving comfort but to a loss in driving safety. Therefore a Proactive Linear Distu...... hiện toàn bộ
Adaptive synchronization of the complex dynamical network with double non-delayed and double delayed couplingInternational Journal of Control, Automation and Systems - Tập 10 - Trang 415-420 - 2012
Yuhua Xu, Wuneng Zhou, Jian-an Fang
To simulate more realistic networks, we introduce a complex dynamical network model with double non-delayed and double delayed coupling and further investigate its synchronization phenomenon in this paper. Based on Lyapunov stability theory, adaptive synchronization criteria is obtained. Analytical result shows that under the designed adaptive controllers, the complex dynamical network with double...... hiện toàn bộ
Direct power control of grid connected voltage source inverters using port-controlled Hamiltonian systemInternational 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
Robust Control for T-S Fuzzy Multi-particle Model of High-speed Train with Disturbances and Time-varying DelaysInternational Journal of Control, Automation and Systems - Tập 20 - Trang 3063-3074 - 2022
Rui Shi, Guangtian Shi
This paper concerns the networked control issue of the speed and displacement of high-speed train (HST) with two independent time-varying delays in presence both in coupler forces and data transmission procedures. The dynamic of high-speed train is firstly described by a group of multiple particle models based on Takagi-Sugeno (TS) fuzzy descriptions. Afterwards, the system states are measured by ...... hiện toàn bộ
Control of a laboratory 3-DOF helicopter: Explicit model predictive approachInternational Journal of Control, Automation and Systems - Tập 14 - Trang 389-399 - 2016
Ju Zhang, Xinyan Cheng, Jiaqi Zhu
A helicopter flight control system is a typical multi-input, multi-output system with strong channel-coupling and nonlinear characteristics. This paper presents an explicit model predictive control (EMPC) for attitude regulation and tracking of a 3-Degree-of-Freedom (3-DOF) helicopter. A state-space representation of the system is established according to the characteristics of each degree-of-free...... hiện toàn bộ
