A very fast direct torque control for interior permanent magnet synchronous motors start upOriginal Research ArticleEnergy Conversion and ManagementSelection of the stator flux command in direct torque control (DTC) of permanent magnet synchronous motors is very important as it affects machine performance. For steady state operation, it can help to decrease the stator current or machine losses. However, in order to get a fast torque response during motor start up, one needs to change b
