| 摘 要： | 从频域角度出发,提出一种兼顾观测带宽和噪声抑制的扩张状态观测器参数整定方法.首先推导传统扰动观测器与线性扩张状态观测器之间的等价关系,将三阶扩张状态观测器的参数整定问题转化为滤波器的设计问题;然后采用切比雪夫滤波器提升观测器性能.仿真结果表明,与已有的扩张状态观测器参数整定方法相比,所提出方法在提高扰动观测能力的同时,具有更好的噪声抑制能力.

| Abstract: | This paper proposes a parameter tuning method of the extended state observer(ESO), which can expand the disturbance observation bandwidth while suppress the measurement noise effectively. Firstly, the equivalence relation between the classical perturbation observer and linear extended state observer is deduced, and the parameter tuning problem of the third-order ESO is transformed into the design problem of a low-pass filter. Then a Chebyshev filter is employed to improve the performance of the ESO. The simulation results show that, compared with the existing parameter tuning method, the proposed method endows the ESO with better noise suppression ability and disturbance observation performance. |
