This paper proposed a nonlinear model predictive control (MPC) method for the control of gantry crane. One of the main motivations to apply MPC to control gantry crane is based on its ability to handle control constraints ...
This paper presents a model-predictive direct power control (MPDPC) strategy for a grid-connected inverter used in a PV system. Thus is aimed at use in distributed generation. The controller uses a system model to predict ...
River basins are the most significant component in water supply grids and are under increasing pressure from competing demands for fresh water. However, unlike energy grids which are managed very efficiently using closed-loop ...
The conventional direct torque control (DTC) method features fast dynamic response, but it also has notable drawbacks such as high torque and flux ripples, variable switching frequency and acoustic noise. The proposed DTC ...
This paper presents a model-predictive direct power control (MPDPC) strategy for a three-phase pulse width modulation (PWM) rectifier. The controller uses a system model to predict the system behavior on each sampling ...
The paper considers the problem of model reduction for a class of linear parameter-dependent (LPD) systems. Three model reduction approaches: balanced truncation, balanced LQG truncation and gain-scheduled $mathcal{H}_infty$ ...

Finite element models of mechanical or structural systems contain too many degrees of freedom (dofs) for dynamic analysis, particularly if the system is nonlinear. This paper presents an investigation on the performance ...
This thesis studies the applicability of the Dynamic model reduction method that is used for direct plant order reduction in the active vibration control of large and flexible structures. A comparison of the performances ...
Basic bilevel programming deals with hierarchical optimization problems in which the leader at the upper level attempts to optimize his/her objective, subject to a set of constraints and his/her follower's solution, and ...

We demonstrate by numerical simulation that the general features of the loss spectrum of photonic crystal fibres (PCF) with a kagome structure can be explained by simple models consisting of thin concentric hexagons or ...

In many mobile robotic manipulation tasks it is desirable to interact with the robots surroundings without actually grasping the object being manipulated. Non-prehensile manipulation allows a robot to interact in situations ...
We develop and characterize new representations for the maxdiff model (Marley & Louviere, 2005) for best-worst choice between multiattribute options; in particular, we state conditions under which the scale value of a ...
Human robot interaction is an emerging area of research with many challenges. Knowledge about human behaviors could lead to more effective and efficient interactions of a robot in populated environments. This paper presents ...
This paper proposes a general model of sustainability, which offers a
comprehensive theoretical framework integrating ecological, economic and
social aspects of sustainability. The model exhibits the underlying ...
The sea mixed wave models of Radar simulators in existence only use the random number produced by computer to simulate simply ..don?t use the statistic discipline and mathematical model, the effect of simulation is not ...
Trilevel programming refers to hierarchical optimization problems in which the top-level, middle-level, and bottom-level decision entities all attempt to optimize their individual objectives, but are impacted by the actions ...
