Robust Projected Adaptive High-Gain Observer for Feedback Control of Buck Converters: Practical ISS

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...

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

Asymptotic Tracking Control of PMSM with Full-State Constraints via Adaptive Event-Triggered Nussbaum-Based Design

Design of robust model predictive control with disturbance observer for conveyor belt drive systems

Conveyor belt drive systems require accurate speed regulation despite disturbances and parameter uncertainty. This study presents the design and evaluation of a Model Predictive Control with Disturbance Observer (MPC--DO) and a Robust Model Predictive Control with Disturbance Observer (RMPC--DO) for a two-mass conveyor...

Linear Active Disturbance Rejection Control Strategy Based on Improved Quasi-Proportional Resonance for the Inner Current Loop of a Grid-Connected Inverter

Nonlinear and asymmetrical loads in microgrids cause severe current distortion and phase unbalance, presenting critical challenges for grid-connected energy storage inverters. Conventional dq-frame Linear Active Disturbance Rejection Control (LADRC) suffers from two key limitations: bandwidth coupling between the obser...

Robust control for electric stabilizer bars via super-twisting sliding mode and active disturbance rejection with fuzzy-modulated adaptive gain scheduling

Electric Stabilizer Bars (ESBs) are widely adopted in high-end vehicles to enhance roll stability during steering. However, most existing studies either neglect actuator dynamics or oversimplify vehicle dynamics, while the combined effects of parameter uncertainties, nonlinearities, and external disturbances are insuff...
