Abstract

The stator flux-linkage and torque double loop control strategy has been used in the traditional two-phase conducting brushless DC (BLDC) motor direct torque control (DTC) system. Based on the study of the control system, this paper presents a new space voltage vector switching table and new methods for the stator flux-linkage amplitude given and estimation. The improved control scheme obtained by the application of the methods and switching table to the double loop control system, can effectively control the stable operation of BLDC motors, and the scheme is verified by the experimental results.
