| 中文摘要: |
| 为有效解决二阶线性系统的时变参数与外部干扰的控制问题，提出采用自抗扰控制方法对系统进行鲁棒跟踪控制。以经典的串联RLC电路为研究对象，在考虑时变参数、外部干扰及其他不确定性因素的基础上，建立二阶系统模型；根据模型设计自抗扰控制器，其工作原理是通过扩张状态观测器实时观测系统扰动，进而补偿到自抗扰控制器中用以抑制扰动。应用Matlab进行系统仿真分析，验证了所设计控制器的有效性。 |
| 英文摘要: |
| To solve the control problem of the time-varying parameters and external disturbances in the second-order linear system,the active disturbance rejection control (ADRC) method is proposed for a robust tracking control about the system. In this paper, the classical RLC circuit as the research object,a second-order system model is first established after considering some uncertain factors, such as time-varying parameters,the external disturbances and the others. Then, ADRC is designed according to the model, with the working theory that the system disturbances are observed in real time by the extended state observer(ESO)and are to be compensated to ADRC for disturbance suppression. The system simulation analysis based on Matlab proves the effectiveness of the designed ADRC. |
