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
Robust control design of a class of nonlinear systems in polynomial lower-triangular formInternational Journal of Control, Automation and Systems - Tập 7 - Trang 41-48 - 2009
Bing Wang, Haibo Ji, Jin Zhu
This paper investigates the problem of global robust stabilization for a wide class of nonlinear systems, called polynomial lower-triangular form (pLTF), which expands LTF to a more general case. The aim is explicitly constructing the smooth controller for the class of systems with static uncertainties, by adding and modifying a power integrator in a recursive manner. The pLTF relaxes the restrict...... 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
