Information
Permanent magnet synchronous machine drive with MTPA control specifically designed for isotropic machines.
Initially the transient has low speed and no Id is needed: the control chose therefore Id=0.
Later speed increases and the control logic requires a negative Id to control machine voltage.
Here control on current amplitude is implemented, which becomes active during the central part of the simulation; in this case only part of the requested toque is delivered.
