The preferred current reference is completely dependant on the torque-current-position characteristics of the machine. Due to the nonlinear nature of the machine, a square current reference often is not the desired shape.

Moreover, the switching period often is responsible for a good part of torque ripple, thus, the use of torque sharing strategies, for example, is necessary.

I agree, The optimal current reference depends on the machine's torque-current-position properties. Due to the machine's nonlinear nature, a square current shape as a reference is not always desirable.
