This work presents the design of continuous and discontinuous output regulators for a magnetic levitation (MAGLEV) system, for asymptotic output trajectory tracking and disturbance rejection. The nonlinear full information case is considered for both regulators. Then by numerical simulations one compares the performance of both control strategies, under criteria as transient response, steady-st...

It is well known that sliding mode control is capable of tackling systems with uncertainties. However, the discontinuous control signal causes a significant problem of chattering. An algorithm is proposed in this paper to eliminate chattering by removing the discontinuous control signal when the system is operating near the sliding plane. The transient performance as well as the robustness prop...

We study a zero-range process where the jump rates do not only depend on the local particle configuration, but also on the size of the system. Rigorous results on the equivalence of ensembles are presented, characterizing the occurrence of a condensation transition. In contrast to previous results, the phase transition is discontinuous and the system exhibits ergodicity breaking and metastable ...

Abstract. In this paper, the analysis of the superconvergence property of the discontinuous Galerkin (DG) method applied to one-dimensional time-dependent nonlinear scalar conservation laws is carried out. We prove that the error between the DG solution and a particular projection of the exact solution achieves (k+ 3 2 )-th order superconvergence when upwind fluxes are used. The results hold tr...

We study a quantum theory based on two assumptions: In the intrinsic frame of reference of an isolated, macroscopic system, (i) the system has no global motion and is not entangled with any other system, (ii) time evolution of statevectors of systems outside the system satisfy Schrödinger equation. A process of collision-type interaction between a microscopic system and a macroscopic system is ...

In the present study, Adaptive Neuro–Fuzzy Inference System (ANFIS) approach was applied for predicting the heat transfer and air flow pressure drop on flat and discontinuous fins. The heat transfer and friction characteristics were experimentally investigated in four flat and discontinuous fins with different geometric parameters including; fin length (r), fin interruption (s), fin pitch (p), ...
