This paper studies the problem of fuzzy adaptive event-triggered control for a class of pure-
feedback nonlinear systems, which contain unknown smooth functions and unmeasured …

In this research, a robust feedback linearization technique is studied for nonlinear processes
control. The main contributions are described as follows: 1) Theory says that if a linearized …

The extended state observer (ESO) plays an important role in the design of feedback control
for nonlinear systems. However, its high-gain nature creates a challenge in engineering …

In this paper, a boundary control scheme is developed for a vibrating flexible string system
subject to input deadzone and external disturbance. First, a basic boundary control scheme …

A combined fractional tracking controller based on backstepping and active disturbance
rejection control (ADRC) is proposed in this work to control uncertain fractional-order …

The multi-motor servomechanism (MMS) is a multi-variable, high coupling and nonlinear
system, which makes the controller design challenging. In this paper, an adaptive robust H …

This paper presents a new design procedure of an optimal nonlinear controller using the
model reference approach. The ball and plate system is used as nonlinear, uncertain, and …

Taking dead-zone nonlinearlity and external disturbances into account, an active
disturbance rejection optimal controller based on a proportional-derivative (PD) control law …

Failure to counteract in-flight actuator stuck failures within a limited amount of time can result
in catastrophic consequences. Aircraft safety is also undermined when fault-tolerant control …

Metaheuristic optimization approach has become the new framework for control synthesis.
The main purposes of the control design are command (input) tracking and load …
