Nonsmooth Modeling and Simulation for Switched Circuits
ABSTRACT Nonsmooth Modeling and Simulation for Switched Circuits concerns the modeling and the numerical simulation of switched circuits with the nonsmooth dynamical systems (NSDS) approach, using piecewise-linear and multivalued models of electronic devices like diodes, transistors, switches. Numerous examples (ranging from introductory academic circuits to various types of power converters) are analyzed and many simulation results obtained with the INRIA open-source SICONOS software package are presented. Comparisons with SPICE and hybrid methods demonstrate the power of the NSDS approach. Nonsmooth Modeling and Simulation for Switched Circuits is intended to researchers and engineers in the field of circuits simulation and design, but may also attract applied mathematicians interested by the numerical analysis for nonsmooth dynamical systems, as well as researchers from Systems and Control.

ABSTRACT: In this work we study the following problem: given a numerical method (an extended $\theta $ θ -method named the $(\theta , \gamma )$ ( θ , γ ) -method), find the class of dissipative linear complementarity systems such that their discrete-time counterpart is still dissipative, with the same storage (energy) function, supply rate (reciprocal variables), and dissipation function. Systems with continuous solutions, and with state jumps are studied. The notion of numerical dissipation is given a rigorous meaning.Numerische Mathematik 12/2013; · 1.33 Impact Factor
