Abstract

Vector control which is high-performance instantaneous torque control for permanent magnet synchronous motors (PMSMs) has been widely used in industry applications, electric vehicles (EVs), and etc. In addition, to achieve the high-speed operation of these applications, the flux weakening control must be used, and single pulse operation is desirable from the viewpoint of reducing switching loss and increasing the output voltage of the inverter. In the single pulse operation, the voltage amplitude is fixed and the torque must be controlled using only the voltage phase, which results in a strong nonlinearity. For designing a controller, a linearized PMSM model with pre-measured currents of operating point was proposed, however, the torque response sometimes does not match time constant of the designed controller. Here, the authors propose a novel method to design the controller based on the Ferrari’s method in which the torque response can be specified. The effectiveness of the proposed controller is verified through simulations and experiments.
