Abstract :
A simulation package, TARDIS, intended for simulating electrical drive systems on a digital computer is described. The core of TARDIS is a general-purpose differential-algebraic equation solver that can handle discontinuities efficiently and differential-algebraic equations of index 0 and 1. Designed to emphasize accuracy and efficiency, TARDIS incorporates several new features: local truncation error control, modeling of discrete components by state machines, zero location, and sparse matrix techniques. As an illustration of its ability to handle complex drive systems with many switching elements, some of the results are presented from a simulation of a complete current source induction motor drive, both a rectifier with finite source impedance and an inverter.<>
