This paper proposes an EXP‐PI controller as a practical alternative to the conventional PI controller, integrating EXP functions on the error and its rate within the control structure. The controller is optimized using five recent intelligent algorithms, with SFS providing the most effective parameter tuning.

Observers Design For Sensorless PMSMs
A state observer is proposed for permanent magnet synchronous motors (PMSMs). The gain of this observer involves a design function that has to satisfy some mild conditions which are given. Different expressions of such a function are proposed. Of particular interest, it is shown that high gain observers and sliding mode like observers can be derived by
