Description

The SRM Hysteresis Current Controller block implements hysteresis current control for the Switched Reluctance Machine (SRM) block.

Ports

Input

IsRef — Reference current

scalar

Reference current for control.

Data Types: single | double

iabc — Measured current

vector

Measured three-phase current.

Data Types: single | double

Reset — Integrator reset

scalar

External reset signal (rising edge) for the integrator.

Data Types: Boolean

theta — Theta-rotor angle

scalar

Rotor angle in the interval [0, β ].

Data Types: single | double

thetaON — Switch-on angle

scalar

Angle for switching on the phase supply.

Data Types: single | double

thetaOFF — Switch-off angle

scalar

Angle for switching on the phase supply.

Data Types: single | double

Output

Sabc — Voltage switch signal

vector | 0 or 1

Signal for switching on and off the three-phase voltage.

Data Types: single | double

Parameters

Torque capability angle (rad) — Torque capability angle

pi/2 (default) | [0, 2*pi/number of rotor poles]

The torque production capability of one rotor pole, in radians.

Hysteresis band (A) — Hysteresis bandwidth

5 (default)

Hysteresis band, h, for the current controller. The switch-on point is h/2 and the switch-off point is -h/2.

Sample time (-1 for inherited) — Block sample time

-1 (default) | positive scalar

Time, in s, between consecutive block executions. During execution, the block produces outputs and, if appropriate, updates its internal state. For more information, see What Is Sample Time? and Specify Sample Time.

If this block is inside a triggered subsystem, inherit the sample time by setting this parameter to -1. If this block is in a continuous variable-step model, specify the sample time explicitly using a positive scalar.

Model Examples

Switched Reluctance Machine Speed Control

Control the rotor speed in a switched reluctance machine (SRM) based electrical drive. A DC voltage source feeds the SRM through a controlled three-arm bridge. The converter turn-on and turn-off angles are maintained constant.
