Quantum Painlevé Equations: from Continuous to Discrete

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We examine quantum extensions of the continuous Painlevé equations, expressed as systems of first-order differential equations for non-commuting objects. We focus on the Painlevé equations II, IV and V.

Simulation-based verification of bounded-horizon safety for hybrid systems using dynamic number of simulations

open access: yesIET Cyber-Physical Systems, 2019
The authors present a simulation-based bounded-horizon verification framework for hybrid systems with Lipschitz continuity on the continuous dynamics. In this framework, the bounded initial set is covered by a finite set of representative states, whose ...

Modular control-loop detection [PDF]

open access: yes, 2006
This paper presents an efficient algorithm to detect control-loops in large finite-state systems. The proposed algorithm exploits the modular structure present in many models of practical relevance, and often successfully avoids the explicit ...

Conflicts and projections [PDF]

open access: yes, 2007
This paper studies abstraction methods suitable to verify very large models of discrete-event systems to be nonconflicting. It compares the observer property to methods known from process algebra, namely to conflict equivalence and observation ...

Research on Non‐Linearity of H‐Bridge Converter in Magnetic Suspension System Based on LRC Model

open access: yesIET Power Electronics
The power amplifier, which regulates the excitation current, is the pivotal component of the magnetic suspension system. The control loop exhibits chaos and bifurcation phenomena due to the non‐linear characteristics of the switching devices.
