Output Feedback Higher-Order Sliding Mode Controller for a Class of Nonlinear Systems

Observer-based optimal and robust output regulation for nonlinear systems

This paper investigates the output regulation problem using an observer-based inverse optimal controller within the nonlinear servomechanism framework for asymptotic convergence to desired references and rejection of time-varying disturbances generated by an exosystem. To address the practical constraint of full-state...

Fuzzy adaptive feedback linearization and sliding mode control for drone position tracking

Model-Based Disturbance Rejection via Sliding-Mode Control: Continuous-Time Formulation and Proper Implicit Discretization

We propose a robust exact sliding-mode controller for reference tracking with model-based disturbance rejection, where the disturbance is generated by a linear time-invariant model driven by a bounded input and may be bidirectionally coupled with the plant. The controller embeds the internal model principle and its err...

of Birmingham Neural adaptive control for uncertain nonlinear system with input saturation

This paper presents neural adaptive control methods for a class of nonlinear systems in the presence of actuator saturation by introducing alternative state variables and implementing state transformation, which ensures that the controllers can be developed without backstepping methodology.

Multi-Observer Output Feedback Stabilization of a Class of Uncertain Nonminimum-Phase Systems

This paper addresses the challenging problem of output feedback stabilization for nonlinear nonminimum phase (NMP) systems in the presence of parametric uncertainties and external disturbances. The proposed framework integrates three distinct observers: a reduced-order observer for reconstructing the unmeasured states...

A Novel Adaptive Terminal Sliding Mode Tracking Control of Engine Electronic Throttle System Using an Enhanced Observer Under Composite Disturbances

This paper proposes a novel adaptive terminal sliding mode tracking control (ATSMC) strategy integrated with an enhanced super-twisting extended state observer (ESESO) for an engine electronic throttle system (EETS) operating under composite disturbances. First, a nonlinear dynamic model of the ETS is established by co...
