Outline
Addressing the low carrier ratio characteristics of a dual three-phase permanent magnet synchronous motor during high-speed operation, where traditional deadbeat control fails to ensure adequate current control performance, an improved deadbeat predictive current control method has been proposed. This method incorporates a voltage static error compensator to account for discrete model errors and control delays at low carrier ratios. To address motor parameter mismatch, a discrete sliding mode observer is employed to compensate for voltage disturbance errors. Validation through MATLAB/Simulink simulation and prototype experiments demonstrates that the proposed improved deadbeat current control effectively compensates for motor voltage errors under high-speed operation and resistive-inductive parameter mismatch conditions, offering excellent disturbance rejection and enhancing the system control performance and operational efficiency.
