“…It is not necessary to review the details of formulating state equations for this class of problem as these have been widely discussed in the literature [2][3][4][5][6][7][8][9][10][11][12]. It is sufficient to note that a set of first order ordinary differential equations of the following form can be developed: Several conventional approaches are used to solve equations of the form (1).…”

“…There have been numerous papen during the past fifteen years detailing the simulation of various induction motor drive sytems (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)14], both in the steady state [2][3][4][5]9] as well as transiently (6.8]. As is standard today, virtually all simulation methods numerically solve an appropriate set of state equations wherein the motor is modeled using either d-q [2][3][4][5][6] or phase [7][8][9] vanrables.…”

Despite the fact that a variety of state space based simulation techniques have been described in the literature, Manuscript submitted February 1, 1985; made available for printing April 22, 1985. none would be particularly well suited for implementation within a general simulation package, especially one that proposes to use a small computer.…”

A software package that simulates the steady state and transient performance of several induction motor drives is described. Included in the package are converter, inverter and slip energy recovery drives. The simulation incorporates a basis transformed state space formulation that results in a very clean, modular software structure together with significant numerical efficiencies. The method is particularly well suited for implementation on small microcomputer systems. A highly interactive, graphics based implementation that provides a cost effective solution for educational needs is described. Typical results for several drive systems are given to illustrate the capabilities of the package.

This paper presents a generalized formulation for the computer-aided analysis of induction machine drives including feedback controls. A simple circuit model for the induction machine is developed to enhance the conventional drive formulation. This machine model, which can be directly interfaced with any drive circuit configuration, significantly simplifies the commonly used dq formulation. In particular, this model eliminates a general difficulty encountered in the automatic formulation of machine &-terminal constraints imposed by the drive operations.This difficulty considerably limits the development of a general purpose simulation program and its subsequent application for general drive analysis. This paper also proposes an efficient algorithm using a simple nodal approach for automatic formulation of power electronic circuits. This algorithm, combined with the proposed machine circuit model, can easily be used to simulate an arbitrarily configured drive system including the effects of control dynamics. A novel pulse-width-modulated current-source-inverter drive system is employed to demonstrate the efficiency of the proposed formulation. The dynamic and steady state performance of this drive system including an effective harmonic control are simulated. The simulated results ?e experimentally verified.

An exact solution of the state differential quations for a power electronic circuit, incorporating a time discretization and a Basis Transformation, is presented. An eigen value -eigen vector expansion of the system matrix allows for the efficient evaluation of the State Transition matrix and Particular Integral. A binary search algorithm, without requiring the recalculation of the exponential matrix, can be used to obtain the state switching times. The Basis Transformation results in an exact solution when the input forcing function has an arbitrary time variation. Examples that illustrate the features of the method are presented.to the conventional Discrete Time Domain modelling method. The result can be termed the Modified Discrete Time Domain method. As a result of these modifications, the discrete time approach becomes very general as well as being computationally efficient. The closed form derivation of the new algorithm is presented and a comparison with the existing analytical models is provided. The efficiency of the improved algorithm is illustrated by several examples. Finally a step by step procedure of the improved discrete algorithm is outlined for transient, direct steady state or small signal analysis of power electronic circuits and systems.
