V/Hz Control

These examples demonstrate observer-based V/Hz control for synchronous machines [1] and induction machines [2]. The example 2.2-kW PMSM, 2-mass mechanics demonstrates the use of a two-mass mechanics model. Furthermore, the examples 2.2-kW induction motor, diode bridge and 2.2-kW induction motor, LC filter show operation of an induction machine under pure open-loop V/Hz control with a diode front-end rectifier and with an LC filter, respectively.
