The extended state observer (ESO) plays an important role in the design of feedback control for nonlinear systems. It is also the key component in any active disturbance rejection control (ADRC) scheme. However, its high-gain nature creates a challenge in engineering practice in cases where the output measurement is corrupted by non-negligible, high-frequency noise. The presence of measurement noise puts a constraint on how high the observer gain can be, which forces a trade-off between fast convergence of state estimates and quality of control task realization. In this brief, a new approach is proposed to redesign the observer part in order to improve its performance in the presence of noise. In particular, a unique cascade combination of ESOs is developed, which is capable of fast and accurate signals reconstruction, while avoiding over-amplification of the measurement noise. The design stage of cascade ESO is followed by the theoretical analysis and the simulation validation showing improvement over conventional solution in terms of noise attenuation.
