Deux améliorations concurrentes des PID
For control engineers and researchers seeking to improve PID controllers, this paper argues that MFC outperforms ADRC, but the comparison is qualitative without concrete numerical results.
The paper compares Model-Free Control (MFC) and Active Disturbance Rejection Control (ADRC) as improvements to PID controllers, demonstrating through examples that MFC is superior and can handle a wider class of systems more easily.
In today's literature "Model-Free Control," or MFC, and "Active Disturbance Rejection Control," or ADRC, are the most prominent approaches in order to keep the benefits of PID controllers, that are so popular in the industrial world, and in the same time for attenuating their severe shortcomings. After a brief review of MFC and ADRC, several examples show the superiority of MFC, which permits to tackle most easily a much wider class of systems.
