An advanced variable structure control of an electrical drive with sinusoidal brushless motor is proposed. An adaptive model following control loop (AMFC) is set forth in order to rebuild the back e.m.f. coefficient and to cancel the non-linear term due to the back e.m.f. by means of a feed forward compensation. The on-line identification of the back e.m.f. coefficient and the application of an optimal phase advance in the voltage improves the efficiency of the brushless motor. A disturbance observer is considered and suitably modified in order to provide a feed forward compensation counteracting the undesirable disturbance effects.

Abstract

An advanced variable structure control of an electrical drive with sinusoidal brushless motor is proposed. An adaptive model following control loop (AMFC) is set forth in order to rebuild the back e.m.f. coefficient and to cancel the non-linear term due to the back e.m.f. by means of a feed forward compensation. The on-line identification of the back e.m.f. coefficient and the application of an optimal phase advance in the voltage improves the efficiency of the brushless motor. A disturbance observer is considered and suitably modified in order to provide a feed forward compensation counteracting the undesirable disturbance effects.
