Summary: In this article, an optimal torque sharing function (TSF) control method incorporated with improved linear active disturbance rejection control (LADRC) and modified coyote optimization algorithm (MCOA) is introduced and applied in switched reluctance motors (SRMs). The TSF is employed to reduce torque ripple, while the LADRC provides better antidisturbance ability and torque ripple reduction. The MCOA is used to automatically tune the parameters for better comprehensive performance. Comparisons show that the proposed method performs best in torque ripple suppression and anti-interference ability.

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 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.

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: In this article, the active disturbance rejection control approach is applied for the first time to address the disturbance rejection and consensus problems in a class of second-order stochastic multiagent systems with undirected and connected network topology. Extended state observers are designed to estimate the unmeasured states and random total disturbance, and active antidisturbance consensus protocols are proposed to achieve consensus in mean square and almost sure practical sense. Numerical simulations are conducted to validate the effectiveness of the consensus protocols.

Summary: In this paper, two specific linear ADRC structures, namely output- and error-based, are investigated. The former is considered a standard version due to its simplicity and effectiveness, while the latter appeals to practitioners with its similarities to conventional control solutions. This work establishes formal conditions for the equivalence between the two ADRC structures and identifies specific modules within them, facilitating the customization of ADRC-based solutions for applications.
