Active disturbance rejection control for BLDCM based on real-time control gain identification

Active disturbance rejection control( ADRC) has the characteristics of good performance and simple algorithm.Since control gain "b"in ADRC could significantly affect control quality,efficient and stable parameter identifying online could have significance on quality control. A new ADRC of brushless DC motors( BLDCM) is designed based on parameter identification using model reference adaptive system. The main parameter adaptive changing makes the new controller more robust. The simulation results illustrate parameter b could be accurately identified and has better performance compared with traditional ADRC.
