“…A PID-PSS method based on control constraints was created by Lakshmi et al And colleagues to modify the operational stability of the power system stabiliser (PSS). The method was tested using a single machine infinite bus (OMIB) power system on a variety of test cases, and the results revealed that the proposed approach could suppress both static and dynamic mechanical vibrations and that the improved controller's control effect was noticeably superior to that of the conventional controller [14].…”

Robotic arms are frequently utilized in contemporary industrial production since they offer great qualities like high precision and low mass. How to minimize robotic arm tremors in order to maximize their control effect has emerged as one of the most critical issues to be resolved with the continued development of industrial intelligence. The study uses a combination of PID control and an artificial fish swarm technique to optimize the parameters and confirm the simulation control effect based on the kinematic analysis of a six-degree-of-freedom (Six-DOF) modular robotic arm. The findings demonstrated that the suggested fusion approach converges to zero in 80 iterations and has a recall of 0.893 and 0.785 at an accuracy of 0.8 and 0.9, respectively. The robotic arm control system’s average control effect is 42.96 %, which is a respectable control performance. In the second and third studies, the fusion approach stabilized actuator end tremor suppression after 0.01 s and 0.0001 s, respectively. It shows that the technique can effectively suppress robotic arm bearing tremor and has high flexibility for robotic arm tremor suppression, which offers trustworthy technological support for improving the motion control system of industrial robots.

The concept of vehicle-to-grid (V2G) has been applied to residential microgrids (MGs) to play an essential role in regulating terminal voltage and system frequency. For this purpose, a power system stabilizer (PSS) has been selected, which is added to the excitatory system to enhance the dynamic and transient stability performance and to offer damping characteristics adequate for V2G regulation. In this work, three interconnected areas powered by diesel generators are investigated to measure the effectiveness of the proposed V2G scheme with PID-PSS controller that is adapted in a direct manner compared to the conventional MGs without the V2G scheme. The studied islanded residential MGs are consisting of diesel generators that are used as main generation sources, residential loads, and EVs aggregator. The performance of the proposed scheme is examined under the effect of a 3-∅ short circuit fault between areas 1 and 3. The final findings emphasize the superiority of using V2G with adaptive PSS compared to the conventional system without both PSS and the inclusion of V2G in terms of over/undershoot and settling time 'stabilizing faster'.

This work analyzes the stability and performance of an offshore solar-concentrated ocean thermal energy conversion system (SC-OTEC) tied to an onshore AC grid. The OTEC is a system where electricity is generated using small temperature differences between the warm surface and deep cold ocean water. Existing control methods for SC-OTEC systems lack coordination, hindering dynamic stability and effective damping for the synchronous generator (SG). These methods struggle to quickly adapt to sudden disturbances and lack the capability to adequately reject or compensate for such disturbances due to complex control constraints and computational demands. To this regard, a control strategy combining sliding mode control (SMC) and a power system stabilizer (PSS) to improve the SC-OTEC dynamic stability and damping features for the SG. Moreover, an auxiliary secondary automatic voltage regulator is assembled with a non-linear exciter system to provide damping features. The proposed PID-PSS and secondary AVR controller gains are adaptively tuned using a modified whale optimization algorithm with the balloon effect modulation. The studied SC-OTEC is tested through MATLAB/Simulink under a severe 3ϕ short-circuit fault, solar radiation variations, and a change in surface seawater temperature as well as changes in local loads. The final findings approved that the proposed control strategy preserves a strong performance and can mimic effectively the proposed SC-OTEC damping compared to the conventional system.
