PROJECT TITLE :
Optimal State Reference Computation With Constrained MTPA Criterion for PM Motor Drives
This research proposes a procedure that maps a PMSM torque request onto optimal state (current) references. Combining the procedure with a dynamic (current) controller yields a torque controller. The maximum torque per ampere (MTPA) criterion is used to minimize conduction and switching losses. This analysis extends the concept to field-weakening operation to obtain high potency at any machine speed. The ensuing constrained MTPA criterion is formalized as an optimization downside. Since it's troublesome to unravel directly, the maximum and intersection torque subproblems are identified. An algorithm is obtained that maps a torque onto an optimal state reference, and it is sufficiently economical for real-time implementation. This method is compatible with a variety of state (current) controllers with/while not PWM, SPM and IPM machines with saliency and reverse saliency, and a variable dc-link voltage. The proposed procedure depends on a sufficiently correct torque model that may not be provided using rated machine parameters. So, an approach to compute locally optimized machine parameters is proposed that takes magnetic saturation into consideration. The concept is developed on a software-in-the-loop platform and evaluated on an experimental take a look at bench.
