In my model ,Torque controller with FOC is used for IPMSM .FOC has current controller.Current controller have two PID controller.I don't know how to tune two PID at same time.Now torque results have overshoot and under shoot ,and actual torque graph result have delta with request torque(10%).thats why machine speed have delta with request speed.Totque results bandwith have 200%.So.I have to rectify all isuue.So,Please give proper procedure for current controller PID tuning for Torque controller concept for IPMSM.
additional Question:does torque control method have PID block?

Hi adhavan,
there are more than one ways to tune the PID controller. It depends on many factors such as motor parameters, switching frequency, control sample time, sensor gains, etc.
following page may be a good start.

You can follow the steps of the following example in the link below to tune the current controllers at first and then repeat it for the torque controller if necessary.
