A Novel Approach to Trace Time-Domain Trajectories of Power Systems in Multiple Time Scales Based Flatness
This paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. The feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. Thus the computation of the flat output for reduced order model of the synchronous machine with simp...
متن کاملSpin state in the propagation of quantum relativistic particles along classical trajectories
We address the propagation of the spin along classical trajectories for a spin-1/2 particle obeying the Dirac equation with scalar potentials. Focusing on classical trajectories as the exact propagation of wave-function discontinuities, we find an explicit spin-transport law for the case of the Dirac oscillator. In the general case we examine the spin propagation along classical trajectories em...
متن کاملBayesian feedback versus Markovian feedback in a two-level atom
Quantum feedback arises when the environment of an open quantum system is deliberately engineered so that information lost from the system into that environment comes back to affect the system again. Typically the environment is large and would be regarded at least in part as a classical system. In the case where the system dynamics are Markovian in the absence of feedback, the information lost...
متن کاملمطالعه انتشار همدوس لپتونهای باردار ناشی از واپاشی پایون و W بوزون در مکانیک بوهمی
Although charged leptons, contrary to neutrinos, cannot oscillate, exploring whether a coherent superposition of charged lepton states can change to others during the propagation is an important problem in the neutrino oscillation theory. In this paper, we consider electrons and muons coming from the pions and W decays and study their propagation in relativistic Bohmian quantum mechanics. We f...
متن کاملWigner flow reveals topological order in quantum phase space dynamics.
The behavior of classical mechanical systems is characterized by their phase portraits, the collections of their trajectories. Heisenberg's uncertainty principle precludes the existence of sharply defined trajectories, which is why traditionally only the time evolution of wave functions is studied in quantum dynamics. These studies are quite insensitive to the underlying structure of quantum ph...
