“…Viscous Control. Te traditional passive viscous control is validated to be efective in suppressing parametric vibrations when external excitation is small [42] and is widely used in engineering practice. However, linear passive damping is not efcient enough for large-amplitude vibration [36,67].…”

“…Ou and Li [37] proposed two principles for optimising the parameters of semiactive control devices and passive dampers; they used numerical simulations to determine the capacity of semiactive control required to achieve a performance similar to that of active control. With an intelligent control algorithm, a semiactive control device can consume a small amount of external energy to actively adjust its parameters according to the structural response while retaining outstanding control performance [38][39][40][41][42]. Shook et al [39] proposed a superelastic, semiactive base isolation system that provides variable viscous damping that can be altered in real-time for the intelligent amelioration of the superstructure response.…”

As the stay cables of cable-stayed bridges become longer, parametric resonance with a large amplitude is more easily triggered, which becomes a vibration hazard of super-long stay cables. An increasing number of practical applications of vibration mitigation on stay cables demonstrate that vibration control strategies can effectively facilitate hazard mitigation and improve cable-stayed bridge reliability and service life. This study proposes a semiactive control approach to reduce the parametric vibration of super-long stay cables in cable-stayed bridges installed with magnetorheological fluid damper (MRFD). First, using the cable’s gravity sag curve equation, an equation governing the combined stay cable-bridge deck-damper control system was established to consider the effect of the chordwise force of cable gravity. Subsequently, a targeted LQR-based optimal active control law is proposed to provide the target control force in the semiactive control. The parametric influences on the performance of the LQR-based optimal active control were analysed to provide insight into the proposed control strategy. Since the semiactive control could achieve almost the same control efficacy of the targeted optimal active control, a semiactive control strategy employing MRFD is proposed to mitigate the parametric vibration of a super-long stay cable. Based on the proposed semiactive control strategy, the system was attached with the MRFD of the longest cable, S36, in the designed prototype long cable-stayed bridge. The efficacy of the established semiactive control system was also analysed. The analysis results confirm that the proposed semiactive control strategy and designed semiactive control system can perform similar to the LQR-based optimal active control. The semiactive control system attached to the MRFD can mitigate the parametric vibration of super-long stay cables in cable-stayed bridge engineering practice.

Traditional energy-feeding suspensions exhibit a non-adjustable damping characteristic during energy recovery, which can compromise the dynamic performance of the suspension system. To overcome this issue, this paper proposes an energy-feeding variable damping control strategy (EFVD) predicated on an electromagnetic hybrid suspension system. This strategy aims to achieve adjustable damping during energy recovery, reducing energy losses while ensuring optimal suspension performance. Building on a half-vehicle suspension model, we construct a dynamic model of the electromagnetic hybrid suspension. By leveraging an enhanced hybrid-skyhook and ground-hook control algorithm (HSGH), we solve for the target control force. We then design a force distribution controller based on the EFVD strategy, aiming to optimize suspension dynamic performance and energy feeding efficiency. And we conduct a simulation study, measuring power supply efficiency and suspension dynamic performance as key evaluation metrics. The results demonstrate the superiority of the proposed EFVD strategy over conventional passive and active suspension control strategies, highlighting its effectiveness and reliability in maintaining dynamic performance while enhancing energy efficiency. This underscores the potential of the EFVD strategy as a practical solution for future suspension system design and energy management.

This study proposes a main inner loop control technique to address the dynamic response of the electromagnetic suspension during vehicle driving. The genetic algorithm is employed to optimize the control parameters of the linear quadratic adjustment controller in the control main loop, with the aim of achieving the desired control force. In the control inner loop, a closed-loop sliding mode controller is designed based on the exponential approximation law to regulate the current. The Lyapunov function was utilized to assess the stability of the controller in terms of its theoretical feasibility. The simulation results of Matlab/Simulink show that under the given working conditions, compared with the passive suspension, sliding mode control and fuzzy sliding mode control for references, the root mean square value and peak value of the vertical acceleration of the body and the dynamic load of the tire with the improved sliding mode control are significantly reduced, the root mean square value of the dynamic deflection of the suspension was not improved. However, on the whole, the ride comfort of the vehicle has been improved.
