This letter proposes an easy-implementation ultralocal model-based tuning-free controller (UL-TFC) to enhance the speed performance of permanent magnet synchronous motor (PMSM) in scenarios with load inertia variation. The UL-TFC is designed without additionally low-pass filter (LPF), and its performance against inertia and control frequency variations is analyzed. The tuning-free performance of the UL-TFC is experimentally confirmed.
This letter proposes an easy-implementation ultralocal model-based tuning-free controller (UL-TFC) considering control frequency to enhance the speed performance of permanent magnet synchronous motor (PMSM) in scenarios with load inertia variation. The complicated traditional tuning-free controller (TFC) for inertia variation suppression is introduced and the side impact of the control frequency on control performance caused by the low-pass filter (LPF) is analyzed. Then, the UL-TFC is designed without additionally LPF, the coefficient configuration has been introduced and the performance improvement of the UL-TFC against inertia and control frequency variations is analyzed. Finally, the tuning-free performance of the proposed UL-TFC is experimentally confirmed.
