Special Issue Information

Dear Colleagues,

As vehicles become increasingly electrified and intelligent, the dynamics and control of vehicle systems are encountering new challenges. Concurrently, the nonlinear dynamic behavior of complex systems remains at the forefront of current research. It is essential to explore and highlight the latest advancements in this field. The innovations and revolutionary possibilities merit publication and should be shared among colleagues. This Special Issue will provide a comprehensive platform for presenting novel research, case studies, and the latest technological advancements that address the challenges of vehicle dynamics and control in the science word. These include the folling: automotives, railway vehicles, motorcycles, vertical takeoff and landing (VTOL), and special vehicles. The focus will encompass both theoretical studies and practical applications of these concepts.

This topic is closely aligned with the scope of vehicle engineering in Machines, focusing on the publication of innovative technologies applicable to a diverse range of vehicles, including automobiles, trains, and vertical takeoff and landing (VTOL). Additionally, it encompasses advanced technologies that are integral to vehicle system dynamics, such as vibration and noise control, as well as active and semi-active control.

Hub motor-driven vehicles (HMDVs) suffer from poor handling and stability due to an increased unsprung mass and unbalanced radial electromagnetic forces. Although traditional ground-hook control reduces the dynamic tire load, it severely worsens the body acceleration. This paper presents a generalized ground-hook control strategy based on impedance transfer functions to address the parameter redundancy in structural methods. A quarter-vehicle model with a switched reluctance motor wheel hub drive was used to study different orders of generalized ground-hook impedance transfer function control strategies for dynamic inertial suspension. An enhanced fish swarm parameter optimization method identified the optimal solutions for different structural orders. Analyses showed that the third-order control strategy optimized the body acceleration by 2%, reduced the dynamic tire load by 8%, and decreased the suspension working space by 22%. This strategy also substantially lowered the power spectral density for the body acceleration and dynamic tire load in the low-frequency band of 1.2 Hz. Additionally, it balanced computational complexity and performance, having slightly higher complexity than lower-order methods but much less than higher-order structures, meeting real-time constraints. To address time-domain deviations from generalized ground-hook control in semi-active systems, a dynamic compensation strategy was proposed: eight topological structures were created by modifying the spring–damper structure. A deviation correction mechanism was devised based on the frequency-domain coupling characteristics between the wheel speed and suspension relative velocity. For ride comfort and road-friendliness, a dual-frequency control criterion was introduced: in the low-frequency range, energy transfer suppression and phase synchronization locking were realized by constraining the ground-hook damping coefficient or inertance coefficient, while in the high-frequency range, the inertia-dominant characteristic was enhanced, and dynamic phase adaptation was permitted to mitigate road excitations. The results show that only the T0 and T5 structures met dynamic constraints across the frequency spectrum. Time-domain simulations showed that the deviation between the T5 structure and the third-order generalized ground-hook impedance model was relatively small, outperforming traditional and T0 structures, validating the model’s superior adaptability in high-order semi-active suspension.
