| Abstract |
This paper presents a new vector control scheme for inverter-fed permanent magnet synchronous motor suitable for DSP implementation. The design of the control scheme is carried out considering the model of the motor in a stationary two-phases frame of reference. This in order to work directly with measurable currents and voltages. The electromagnetic torque and the reactive power are directly controlled by hysteresis regulators whose outputs are used to generate the command signals of the three-phase inverter. Position sensor and coordinate transformations are not needed, then the signal processing equipment is very simple and the calculation time is reduced. Experimental tests in which the proposed scheme is used to realize the control of the motor with unity power factor are shown. |
