| 摘要: |
| The output regulation approach has effectively addressed the speed tracking and disturbance rejection problem of permanent
magnet synchronous motor (PMSM). Although accurate speed tracking under time-varying load torque disturbance has been
achieved, the number of disturbance frequencies should be known. In this paper, an adaptive observer-based error feedback
control method is proposed, which can solve the speed tracking control problem of PMSM subject to completely unknown multi-frequency sinusoidal load torque disturbance, requiring only the upper bound of the number of disturbance frequencies. The design steps of this method can be divided into the following three steps. In step one, a filtered transformation is applied to convert the observer canonical form of the error system and the transformed exosystem into an adaptive observer form. In step two, an adaptive observer is designed to estimate the unknown parameters of the exosystem and states of the adaptive observer form. In step three, an adaptive observer-based error feedback controller is designed to solve this control problem. The effectiveness of the proposed method is demonstrated by experimental results. |
