| 英文摘要 |
| The amplification of high-frequency measurement noise restricts the gain of extended state observer (ESO)
and affects the estimation accuracy of disturbance. However, the lack of uniform performance comparison among existing
noise suppression ESOs makes it challenging to choose in engineering practice. Therefore, this paper establishes the
disturbance estimation error transmission function for four kinds of noise suppression ESOs and uses the frequency domain
method to systematically analyze the influence rule of the observer bandwidth on the disturbance estimation ability and
noise suppression performance. The practicability of the observers is evaluated comprehensively from six dimensions:
Disturbance estimation accuracy, convergence rate, energy consumption, and noise suppression. Finally, the results of the
theoretical analysis are verified by numerical simulation. The research results of this paper can provide a basis for the
engineering design selection of noise suppression ESO. |
