Description

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

Examples

Control Rotor Speed of Switched Reluctance Machine

Control Rotor Speed of Switched Reluctance Machine

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. To achieve both forward and backward rotation, this example adjusts the converter turn-on and turn-off angles using the speed error.

Ports

Input

Reference current for control.

Data Types: single | double

Measured three-phase current.

Data Types: single | double

External reset signal (rising edge) for the integrator.

Data Types: Boolean

Rotor angle in the interval [0, β ].

Data Types: single | double

Angle for switching on the phase supply.

Data Types: single | double

Angle for switching off the phase supply.

Data Types: single | double

Output

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

Data Types: single | double

Parameters

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

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

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.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
