Abstract
Background:
Precise modeling and control system design are the basis of highperformance
control of dual-winding bearingless brushless DC motors (BL-BLDCM), and the existing
research is relatively few.
Objective:
This paper takes 12-slot/tooth 4-pole BL-BLDCM as the research object, establishes a set
of a detailed mathematical model, and designs the control system of BL-BLDCM.
Methods:
Firstly, the structure of BL-BLDCM and the radial suspension force generation principle
were introduced. Secondly, a set of an accurate mathematical model of BL-BLDCM was established
which was finally verified by static and dynamic finite element method (FEM), the motor body
model and control system were built by Matlab/Simulink software, and the simulation analysis of
control performance was completed.
Results:
The established mathematical model is correct. The BL-BLDCM can generate stable electromagnetic
torque and radial magnetic suspension force, and the control system has strong ability
of resisting load torque disturbance and radial force load disturbance.
Conclusion:
It has certain reference significance for the accurate modeling and control system design
of later BL-BLDCM.
