中文摘要 |
对感应电机直接转矩控制系统中存在的干扰, 本文结合扩张状态观测器(ESO)和有限时间控制(FTC)提出一种复合控制方法来提高系统的抗干扰能力. 首先采用扩张状态观测器估算系统的扰动, 用此观测值作为前馈量
补偿到输入端; 然后运用连续有限时间控制方法设计系统前向通道中的反馈控制器. 文中对控制器的稳定性进行了证明. 与传统的PI控制以及P+ESO控制方法进行仿真与实验结果比较, 验证了方法的有效性. |
英文摘要 |
Existing disturbances in the direct torque control of induction motor drive system, we proposes a composite control scheme based on extended state observer (ESO) and the continuous finite time control (FTC) to improve the disturbance rejection property of the system; the estimated value is used in the feedforward compensation design. Secondly, a continuous feedback-based finite-time control technique is applied to the feedback design. Then, the stability of the controller is analyzed. Simulation and experimental comparisons with other two methods, traditional PI and P ESO, are given to validate the effectiveness of the proposed method. |
