The torque-maximizing field-weakening controlscheme proposed by Kim and Sul is developed further. Theperformance under imperfect field orientation conditions isinvestigated, and it is shown that an overestimated—rather thanan underestimated—model leakage inductance should be used. Aslightly modified algorithm, which offers better robustness andreduced computational complexity, is presented. The importance,for good performance, of combining the scheme with currentand speed controllers featuring antiwindup and improved disturbancerejection is emphasized. The dynamics of the resultingclosed-loop system are analyzed. Obtained in the process are rulesfor selection of all controller parameters, allowing tuning withouttrial-and-error steps. Good performance of the resulting systemis verified experimentally.
