DQ Limiter
Saturate voltages (or current) in the dq reference frame
- Library:
Motor Control Blockset / Controls / Control Reference
Description
The DQ Limiter block generates saturated values of the input voltages (or current) in the dq reference frame, based on the phase voltage (or current) peak limit of the inverter.
The block accepts reference values of d and q axis voltages (or current) and outputs the corresponding saturated values. The block also provides the unsaturated peak value of the reference dq voltages (or current) to enable field weakening control.
Equations
These equations describe the computation of saturated dq voltage (or current) values by the block.
