This paper investigates a novel extended state observer incorporating static dead-zone injection, aiming to mitigate the impact of high-frequency noise on the system by introducing zero dynamics near y-\hat{x}_{1}. In this work, we extend the application of dead-zone injection to disturbance estimat...
