In this paper, a modified LQG technique is proposed for the solution of the robotic visual tracking problem (eye-in-hand configuration). The problem of mbotic visual tracking is formulated as a problem of combining control with computer vision. A crosstorrelation method provides the object's motion measurements which are used to update the system's measurement vector. These measurements arc fed...

Abstract Lossless positive-real systems have been widely studied in the literature. They are which energy is entirely transferred between input and output. In this paper, new aspects related to linear quadratic gaussian (LQG) control of lossless reported including both continuous-time discrete-time cases. Direct formulas for calculation optimal gains will be introduced properties different stru...

Attempts to unify Gravity Theory and Quantum Field (QFT) under Loop (LQG), are diverse; a dividing line between classical quantum is sought with Schrödinger cat-state experiments. A Primordial Theory-based alternative presented, gravity-based harmonic oscillator developed. With theory applied at micro-scales gravity meso- macro-scales, this scale-gap contributes the conceptual problems associat...

The linear quadratic Gaussian (LQG) control for a quadrotor unmanned aerial vehicle (UAV) under false data injection attacks is studied. LQG depends on optimal state estimation, while this type of makes the estimation unimplementable in practice. To address problem, authors prose framework to detect and then augment information controller design. Based framework, designed sufficient condition s...

In this paper, we study the dynamics of k-essence in loop quantum cosmology (LQC). The indicates that gravity (LQG) effect plays a key role only early epoch universe and is diluted at later stage. fixed points LQC are basically consistent with standard Friedmann-Robertson-Walker (FRW) cosmology. For most attractor solutions, stability conditions agreement for FRW universe. But some special poin...

To date, a mathematically consistent construction of effective rotating black hole models in the context Loop Quantum Gravity (LQG) is still lacking. In this work, we start with assumption that LQG metrics can be effectively obtained using Newman–Janis Algorithm. Then, based on few extra fair assumptions seed metric functions, make conjecture what would generically look like. Our general argume...

Based on a recently developed notion of physical realizability for quantum linear stochastic systems, we formulate a quantum LQG optimal control problem for quantum linear stochastic systems where the controller itself may also be a quantum system and the plant output signal can be fully quantum. Such a control scheme is often referred to in the quantum control literature as “coherent feedback ...

Optimal control theory and machine learning techniques are combined to formulate and solve in closed form an optimal control formulation of online learning from supervised examples with regularization of the updates. The connections with the classical linear quadratic gaussian (LQG) optimal control problem, of which the proposed learning paradigm is a nontrivial variation as it involves random ...

We introduce a generic solver for dynamic portfolio allocation problems when the market exhibits return predictability, price impact and partial observability. We assume that the price modeling can be encoded into a linear state-space and we demonstrate how the problem then falls into the LQG framework. We derive the optimal control policy and introduce analytical tools that preserve the intell...

We generalize a model recently proposed for Euclidean quantum gravity to the case of Lorentzian signature. The main features of the Euclidean model are preserved in the Lorentzian one. In particular, the boundary Hilbert space matches the one of SU(2) loop quantum gravity. As in the Euclidean case, the model can be obtained from the Lorentzian Barrett-Crane model from a flipping of the Poisson ...
