“…At the same time, Li et al [97] used artificial McKibben muscles to actuate a TS. In various applications, the equipment with actuators of the TSs is fundamental, using piezoelectric ceramic actuators [98], twisted and coiled [99], dielectric elastomer in the form of tape [100], among others, offering deformations in the structure, that can be controlled electrically, thermally, or magnetically. Hybrid techniques have also been developed, using 3D printing combined with magnetoactive materials to generate shape-changing structures [101].…”

“…This means that modifying the prestress level, is possible to change a material's natural frequencies [58]. As pretensions increase, resonant frequencies are pushed to a higher frequency region where modal damping increases [98]. For example, Figure 8 shows the behavior of a tensegrity cell in a deformation mode, modifying its shape and supporting high loads.…”

Tensegrity is composed of structures that are characterized by compressive elements (bars) and tension elements (cables) that work together to transmit and/or withstand forces in an efficient and balanced manner. Their kinetic analysis, design, and control are study topics with various methods still being explored. Furthermore, research and development have been conducted in different areas such as architecture, engineering, biomechanics and robotics, exploring lightweight and resilient tensegrity structures for more flexible and adaptable movements. Tensegrity is a structure increasingly used and studied in different areas, thanks to its ability to transmit forces efficiently and its versatility in the application of designs and solutions in different areas. So, this review presents initial definitions of this area, as well as recent methods and applications that have been developed and are the focus of study for future advances.

“…On the other hand, for the sake that tensegrities are fexible systems, the mitigation of structural dynamic responses utilizing relevant active control techniques becomes an ongoing topic in the design of real tensegrities [37][38][39][40][41][42][43][44][45]. Several works have been reported on numerical simulation of small and simple tensegrity models.…”

Active vibration control of tensegrity structures is often challenging due to the geometrical nonlinearity, assemblage uncertainties of connections, and actuator saturation of controllers. To tackle these technical difficulties, a fast model predictive control (FMPC) strategy is herein implemented to effectively mitigate the structural vibration. Specifically, based on the explicit expression form of the Newmark- β method, the computation of the matrix exponential is avoided and replaced by one online and two offline transient analyses at each sampling instant on the structure, and the optimal control input is attainted from the second-order dynamic equation without forming an expanded state-space equation. Meanwhile, the artificial fish swarm algorithm (AFSA) is embedded to automatically derive optimal arrangement of actuators with the selection of a reasonable objective function. Two illustrative examples, including two standard and clustered tensegrity beams and a clustered tensegrity tower, have been fully investigated. The outcomes from illustrative examples prove the effectiveness and feasibility of the proposed method in optimal active vibration control of tensegrity structures, implying a promising prospect of the investigated approach in analyzing and solving relevant engineering problems.

“…For space structures, the vibration control method can be divided into two categories: active and passive control. Active control [6][7][8] introduces an automatic control system with an additional power supply to dampen the vibration amplitude. It can provide optimal vibration control effect under some specific conditions, but the control system is complex, and it is hard to obtain enough power in space.…”

Modular space structure has become a research hotspot in the aerospace field. In the microgravity and weak damping space environment, modular space structures may continuously vibrate due to the transient excitation caused by satellite attitude adjustment or space debris impact, which will make the structure unstable. Therefore, a passive vibration control method based on band gap design is proposed for the modular space structures. Firstly, a modular spectral element model based on the super element is established, and the modular spectral element model is expanded into modular space structures. Then, band gap characteristics of the modular space structure are analyzed and optimized to improve the wave isolation ability. The numerical simulation shows that the elastic wave in the band gap can be effectively isolated and the band gap is significantly improved by optimizing structural parameters.
