LESO-Based Nonlinear Continuous Robust Stabilization Control of Underactuated TORA Systems
Actuators, 2022 In this paper, we consider the robust stabilization control problem of underactuated translational oscillator with a rotating actuator (TORA) system in the presence of unknown matched disturbances by employing continuous control inputs.

Journal of Ecology, Volume 114, Issue 3, March 2026.Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Phase‐Advanced ADRC: Precision Missile Attitude Control via Delay Compensation
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This paper proposes measurement delay compensated phase‐leading linear active disturbance rejection control (MPLADRC) with a novel observer (MPLESO) integrating synchronized input filtering and phase‐lead compensation. This framework eliminates temporal signal mismatch and phase lag in missile attitude control, achieving zero steady‐state error for ...

Damping Compensation for Active Vibration Isolation System With Active Disturbance Rejection Control
IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.The analysis of classic active disturbance rejection control (ADRC) for active vibration isolation systems (AVIS) with electromagnetic actuators demonstrates that directly applying ADRC to these systems has some shortcomings. To overcome the limitations of classic ADRC in AVIS with electromagnetic actuators, damping compensation is proposed to enhance ...
