Description

The PMSM Configuration block generates the configuration signal for a permanent magnet synchronous machine/motor (PMSM). This signal can be used to update parameters of PMSM blocks that support FPGA deployment, for example, PMSM HDL.

Model 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).
