Maximum Torque per Ampere Control for Permanent Magnet Synchronous Motor Drive using FOPID Controller

PMSM is being more effective than induction motor of same size as it does not require rotor current. Out of its two type that are surface and interior, interior PMSM motors has higher saliency which can be effectively used in achieving higher torque at the particular speed. Many parameters change with time such as inductance, which leads to non-linearity in system and increase the complexity in control system. Fractional order PID controller can be used in such a situation to expand the controlling range of the system. FOPID provide wide range of controlling as compare to PID controller. This feature of FOPID can be utilized in MTPA control of permanent magnet. Use of FOPID in the system will reduce transient effect and also the steady state error as compare to conventional PID controller which will help in improving the optimum efficient system of a MTPA control of machine.
