| 英文摘要 |
| In this paper, a higher-order disturbance observer is designed to estimate external disturbance, and a pole
placement control method based on the higher-order disturbance observer is proposed for a class of single-input singleoutput
discrete-time linear systems with external disturbance. The method consists of a conventional pole assignment
controller and a higher-order disturbance observer. The conventional pole assignment controller is used to ensure the
stability of the closed-loop system, and places its poles to the ideal position. The higher-order disturbance observer is
used to compensate the influence of external disturbance on the closed-loop system. Theoretical analysis, simulation and
experimental results in a water-tank level system show the effectiveness and superiority of the proposed method. |
