An approximate dynamic programming (ADP) strategy for a dual adaptive control problem is presented. An optimal control policy of a dual adaptive control problem can be derived by solving a stochastic dynamic programming problem, which is computationally intractable using conventional solution methods that involve sampling of a complete hyperstate space. To solve the problem in a computationally...

this review paper presents closed loop control techniques for controlling the inverter working under different load or KVA ratings. The control strategy of the inverter must guarantee its output waveforms to be sinusoidal with fundamental harmonic. For this purpose, close loop current control strategies such as H∞ repetitive controller, dual closed-loop feedback control, Adaptive Voltage Contro...

A purely topological approach for the generation of hexahedral meshes from quadrilateral surface meshes of genus zero has been proposed by M. MüllerHannemann: in a first stage, the input surface mesh is reduced to a single hexahedron by successively eliminating loops from the dual graph of the quad mesh; in the second stage, the hexahedral mesh is constructed by extruding a layer of hexahedra f...

The paper presents “A CMOS Delay Lock Loop with Dual Control”. Positron emission tomography (PET) with time-of-flight (TOF) capability has been shown to provide a better reconstructed image compared to conventional positron tomography. Resolution is the biggest problem in PET. To achieve such resolution, time interpolations and multiphase sampling techniques are the mostly used methods. A preci...

The problem of designing an iterative learning controller in the presence of input uncertainties is of great importance in practical implementations. This paper addresses this important issue for a simple scalar nonlinear dynamic system with general input uncertainties. A dual iterative learning loop is applied to systems to “learn” both unknown dynamics and static input uncertainties respectiv...

In the paper hep-th/0504039, it was conjectured that in the context of the AdS/CFT correspondence, the 1/2-BPS point-like Wilson loop in the N = 4 SYM theory is mapped to the vacuum state of the dual IIB string theory on the pp wave background and the functional derivatives of the Wilson loop are mapped to the excited string states. Motivated by this conjecture, we consider the small deformatio...

In this paper we consider discrete-time nonlinear systems that are affected, possibly simultaneously, by parametric uncertainties and disturbance inputs. The min-max model predictive control (MPC) methodology is employed to obtain a controller that robustly steers the state of the system towards a desired equilibrium. The aim is to provide a priori sufficient conditions for robust stability of ...

From an operations standpoint, the most important task of a traffic surveillance system is determining reliably whether the facility is free flowing or congested. The second most important task is responding rapidly when the facility becomes congested. These tasks are complicated by the fact that conventional vehicle detectors only monitor discrete points along the roadway. The detectors are ty...

In this paper we study the oneand two-loop corrections to the four-point amplitude of N = 6 Chern-Simons matter theory. Using generalized unitarity methods we express the oneand two-loop amplitudes in terms of dual-conformal integrals. Explicit integration by using dimensional reduction gives vanishing one-loop result as expected, while the twoloop result is non-vanishing and matches with the W...
