The accurate prediction of coupled inductive and capacitive effects in electromagnetic coils is crucial importance many industrial applications, due to the increase operating frequency or voltage levels. In this paper, we propose a light-weight electric circuit model that avoids solving large 3D Maxwell full-wave problem, still able predict not only first resonance but also next few resonances ...

This paper presents new features recently added to a general-purpose surge simulation code based on the FDTD (Finite Difference Time Domain) method. The added features include various-shape conductor models, lumped-parameter circuit-element models, a lightning-channel model, and an integrated analysis environment (IAE). For precisely modeling the shapes of various conductors, the following cond...

The problem of constructing model reference adaptive H∞ control for flexible arms is considered in this manuscript. Control schemes of flexible arms are mixed parameter systems composed of distributed parameter systems of hyperbolic type (flexible arms) and lumped parameter systems (motor control systems). Owing to infinite dimensional modes of distributed parameter systems, control of those co...

This paper presents a new approach for the modelling of a screw shaft including the axial and torsional dynamics in the same model. The model includes the distributed parameter dynamics of the ball screw system and the effect of mass distribution. This is based on the flexibility of the Transmission Line Matrix Method (TLM) to develop lumped and distributed parameter systems. The procedure for ...
