Summary: The paper proposes a fast frequency recovery-oriented distributed optimal control strategy that integrates dynamic algorithms and active disturbance rejection control algorithms to optimize frequency control and economic dispatch in nested multiple-microgrids. The distributed optimal control law derived from this integration effectively coordinates microgrids to share power economically during frequency regulation, alleviating communication and computation burden. Numerical simulations verify the effectiveness of the proposed strategy compared to conventional distributed PI-based optimal control strategies.

Summary: This paper investigates a robust reduced-order method for active disturbance rejection control (ADRC) to improve control performance. A modified noise reduction disturbance observer (MNRDOB) is proposed to enhance the robustness of closed-loop systems. Simulations demonstrate the robustness and noise suppression effects of the compound control method, and parameter tuning method for the MNRDOB is provided. Experimental results on a one-dimensional gimbal show excellent performance in overshoot, tracking accuracy, and disturbance attenuation.

Summary: This article presents a new method that uses the active disturbance rejection control (ADRC) paradigm to address the control problem for a specific type of non-linear systems with unknown disturbances and measurement noise. An improved extended state observer (ESO) is introduced to separate disturbance estimation from state reconstruction, with a new parameter for independent adjustment of disturbance-rejection performance. The method is validated through simulation and experimental results, demonstrating its superiority in disturbance rejection and noise suppression compared to traditional methods.

Summary: This research aims to develop a novel method for the active control of combustion oscillation based on active disturbance rejection control (ADRC). The effectiveness of parameter tuning and the controller in suppressing combustion oscillation was studied by simulation and experiments. The experimental results show that the first-order ADRC performs better than the proportional-integral-derivative (PID) controller, while the second-order ADRC exhibits a better pressure-suppression effect and smaller controller output voltage.

Summary: This paper investigates secure control of Networked Inverted Pendulum Visual Servo Systems (NIPVSSs) based on Active Disturbance Rejection Control (ADRC). The limitations of the traditional Single-Input-Single-Output (SISO) ADRC in NIPVSSs with disturbance are revealed and a new Single-Input-Multi-Output (SIMO) ADRC method is proposed. The proposed method reduces steady-state error and achieves stable control of both pendulum angle and cart position.

Summary: This paper treats landing gear and magnetorheological damper (MRD) as a whole and designs several specific model-independent control strategies based on error feedback to absorb vibration energy and inhibit shimmy. To improve the performance of active disturbance rejection control (ADRC), phase compensation active disturbance rejection control (PCADRC) is proposed. Simulation results show that the proposed method has greater control effect compared with others, and PCADRC also exhibits good robustness and disturbance rejection properties against parameter perturbation and external disturbance.
