Optimum control system of pmsm with field weakening by variable voltage supply

M. Mandzyuk, I. Shchyr

The paper presents an algorithm for motor control by electric drive based on synchronous motor with permanent magnets (PMSM), which ensures maximum energy efficiency. The algorithm was tested by computer simulations using field weakening with different supply voltages
