Description

The Hysteresis Current Controller (Three-Phase) block implements three-phase hysteresis current control for power converters.

Examples

BLDC Hysteresis Current Control

BLDC Hysteresis Current Control

Control the currents in a BLDC based electrical drive using hysteresis controllers. A DC voltage source feeds the BLDC through a controlled three-phase inverter. A ramp of current request is provided to the motor controller. The load torque is quadratically dependent on the rotor speed. The Control subsystem implements the hysteresis-based current control strategy. The Scopes subsystem contains scopes that allow you to see the simulation results.

Parameters

expand all

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.
