Description

The Induction Motor Configuration block generates the configuration signal for an induction machine or motor. You can use this signal to update the parameters of induction motor blocks that support FPGA deployment, such as the Induction Motor HDL block.

Examples

Field-Oriented Control (FOC) of PMSM Using Hardware-In-The-Loop (HIL) Simulation

Uses hardware-in-the-loop (HIL) simulation to implement the field-oriented control (FOC) algorithm to control the speed of a three-phase permanent magnet synchronous motor (PMSM). The FOC algorithm requires rotor position feedback, which is obtained by a quadrature encoder sensor. For more information on FOC, see Field-Oriented Control (FOC).
