Selection of stator flux command in DTC of permanent magnet synchronous motors is very important as it affects the machine performance. For steady state operation, it can help to decrease stator current or machine losses; however, in order to get a fast torque response during motor start up, one needs to change both stator flux angle and magnitude. In this paper, a method is presented to find the optimal voltage vectors to change both flux angle and its magnitude which results in high dynamics… CONTINUE READING
