摘要：

This work proposes a new switching strategy for field oriented control of motor driver to minimize the power of filtered error. By modifying pulse-width resolution and system operating frequency, the switching number is reduced without sacrificing the speed performance. Noise shaping induced by different sampling rates is analyzed. Conventional space vector pulse width modulation is shown to be a special case of the proposed strategy. Another case with zero-bit pulse-width resolution, MDFQM, is proposed. Experimental results show that MDFQM can reduce switching number and heat dissipation of transistors. This property enhances the control efficiency, reliability and durability of power stage. (C) 2011 Elsevier Ltd. All rights reserved.
