The piezoelectric smart structures, which can be labeled as the cream of the crop of smart
structures without overstatement, are strongly impacted by a large number of uncertainties …

The active disturbance rejection control (AD RC), first proposed by **gqing Han in late
1980s, is a powerful control technology being able to deal with external disturbances and …

In this paper, we develop a novel extended state observer (ESO), in terms of tracking error
only, for output tracking of a class of multi-input multioutput systems with mismatched …

This article investigates a class of linear–nonlinear switching active disturbance rejection
control (ADRC) to design speed controllers and current controllers for permanent magnet …

The trajectory tracking performance of a quadrotor is affected by the load variations, wind
gusts, inaccurate model parameters, etc. This study proposes a novel robust trajectory …

Uncertainties, especially mismatched uncertainties, pose great challenges to high accuracy
tracking controller design for mechanical servosystems. In this article, a novel recursive …
