# SRM

Model of Switched Reluctance Motor

## Library

Electromechanical Drives

## Description

Model of Switched Reluctance Motor is in the five variants, created by

- Simulink blocks (SRM Block)

- S-function Lvel-2 in language C as continous (SRM continous)

- S-function Lvel-2 in language C as discrete (SRM discrete)

- S-function Lvel-2 in language M as continous (SRM continous)

- S-function Lvel-2 in language M as discrete (SRM discrete)

## Data Type Support

The block of SRM accepts only one dimension input signals and any numeric data type supported by Simulink software. Three-phase stator currents represents single vector output.

## Parameters and Dialog Box

Input parameters

  Enter the value of parameters or mark checkbox, if you want created new input insted of parameter.

Sample time (Only in discrete type of model)

  Enter the time interval between sample time hits. Model use Euler method.

Magnetic flux

  Magnetic flux is defined as table by phase current and rotor position. Table can be loaded from workspace or from Mat-file. If table is loaded from Mat-file, then Mat-file must be in the current directory. Table must be defined excatly as shown on the next figure and motor position must be directly from interval <45;0> degres. Bilinear interpolation is used for estimation actual values.

Non zeros initial conditions

  After this button is clicked, new window is opened. Enter the value of initial state variables. Default values of initial conditions are set to zero.

Output paramters

  You may add another outputs to block.
