3-Phase AC Induction Motor Control V/Hz
Application - Closed Loop
This application demonstrates a principal of the Volts per Hertz (V/Hz) control of the 3-Phase
AC Induction motor in closed-loop using the 56F8346EVM board, Optoisolation board, and
3-phase AC BLDC high-voltage power stage.

Specifications
This application performs principal control of the 3-phase AC induction motor using the 56F8346
processor. The control technique sets the speed (rpm or Hz) of the magnetic field and calculates the
phase voltage amplitude according to a V/Hz table. This table is private to the application and reflects
AC induction motor parameters (Base Voltage/frequency; Boost Voltage/frequency; DC Boost
Voltage). The incremental encoder is used to derive the actual rotor speed.
The closed-loop system is characterized by a feedback signal (Actual speed), derived from a
quadrature decoder in the controlled system. This signal monitors the actual behavior of the system,
and is compared with the reference signal (Required Speed). The magnitude and polarity of the
resulting error signal are directly related to the difference between the required and actual values of the
controlled variable, which may be the speed of a motor. The error signal is amplified by the controller,
and the controller output makes a correction to the controlled system, reducing the error signal.
Protection is provided against drive faults Overcurrent, Overvoltage, Undervoltage, and Overheating.
