摘要
In the interior permanent magnet synchronous motor (IPMSM) drive system, the conventional linear active disturbance rejection controller (C-LADRC) is affected by the bandwidth, which will lead to insufficient tracking and disturbance compensation capability. To solve the above problem, a doubly-fed differential compensation LADRC (DFDC-LADRC) combined with input feedforward differential compensation and output feedback differential compensation signals is proposed in this article. The DFDC-LADRC takes the total disturbance error as the basis for adjusting the total disturbance of linear extended state observer (LESO), while an output feedback differential compensation signal is introduced so that the total disturbance received by the system can be effectively estimated and compensated by LESO. In DFDC-LADRC, the actual value of the output signal is directly taken as the feedback signal of the linear state error feedback (LSEF), and the input differential compensation signal is given simultaneously, so as to reduce the observation burden of LESO and enhance its tracking capability. Finally, the correctness and effectiveness of DFDC-LADRC are verified by theoretical analysis and experiments.
