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.

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

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

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
