Low-power PMSMS (permanent magnet synchronous motor with sinusoidal excitation) drive systems are standard equipped with PWM inverter which employ a diode rectifier front-end (has not a regenerative unit) to supply the ac power from the mains to the dc link. This paper proposes an algorithm to generate the optimum d- and q-axis reference currents for four quadrant operation of PMSMS drive system,...
In this study, adaptive tracking control (ATC) is presented for a toggle mechanism of electric injection molding machines in the presence of uncertainties and disturbances during closing operations. The controls are developed based on mathematical knowledge of the toggle mechanism and the permanent magnet synchronous motor (PMSM). The proposed controls are robust not only to parametric uncertainties...
In this paper, a nonlinear control has been developed for a permanent magnet synchronous motor (PMSM), in order to perform tasks with minimal execution time. This control method takes in consideration the PMSM limitations' constraints: stator's current must be within the safety specifications. PMSM's nonlinear model is proposed. Nonlinear control methods have been developed for the various states...
