In the article, the adaptive composite dynamic surface neural controller design problem for
nonlinear fractional-order systems (NFOSs) subject to delayed input is discussed. A …

Different from traditional adaptive fuzzy control, this paper introduces a composite learning
adaptive backstep** fuzzy control method using historical data which mainly focuses on …

This article studies the predefined‐time observation problem of generalized strict‐feedback
second‐order systems commonly encountered in practice. A nonaffine control input, a …

This paper studies the hybrid event-triggered tracking control based on an unmanned
autonomous helicopter (UAH) and an unmanned ground vehicle (UGV) under …

The powerful control ability of the active disturbance rejection control (ADRC) method has
attracted much attention from both the academic and industrial communities. This method …

A fractional-order proportional-integral-derivative (FO-PID) with two more fractional-order
operations can achieve higher control performance than a proportional-integral-derivative …

The harsh actual working environment and heavy weight of the electric shovel pose a great
challenge to its trajectory tracking performance. Taking into account the strong robustness …
