LADRC-KALM Control Method Research for Three-motor Synchronous System

摘要

A linear active disturbance rejection control compound Kalman filter (LADRC-KALM) control method was proposed aiming to three-motor synchronous system in this paper. The system was controlled by the use of ADRC's strong anti-interference ability and decoupling performance. The observation results of extended state observer (ESO) would be affected if the measuring noise was not taken into account. Thus, the output feedback signal must be filtered by Kalman filter before entering ESO of ADRC. System simulation and experimental results showed that many control indicators of LADRC-KALM were significantly better than the one of linear disturbance rejection control (LADRC).
