Abstract :
This paper describes the research and development of a control system in digital valve electric actuator driven by a BLDCM (brushless DC motor). A new method is studied and applied to control the torque and flux of the BLDCM with trapezoidal back EMF, which can significantly suppress the undesired torque pulsation. The principle of designing of the hardware and software for control system in valve electric actuator is also given. The experiment results showed that this developed control system, including digital signal processor (DSP) and intelligent power module (IPM), has good performance in speeding and positioning
