Abstract
The present disclosure discloses a method, a controller, and a motor drive system for suppressing electromechanical coupling resonance, relates to the technical field of electromechanical control. The present disclosure includes constructing a dynamic model of a mechanical system; constructing a control algorithm model of a control system: determining a mathematical model of a control object in the control system, including a mathematical model of a permanent magnet motor and an inverter, and designing a motor controller for the mathematical model; constructing an electromechanical coupling model based on the dynamic model of the mechanical system and the control algorithm model of the control system; and carrying out resonance characteristic analysis of an electromechanical system based on the electromechanical coupling model to determine resonance points. The method proposed in the present disclosure combines ADRC, ensuring good control performance when motor parameters change, and robustness against changes of PMSM parameters.
