“…The optimization of evaporation, being considered as the most efficient physiological means for heat dissipation, has also been the subject of studies on the development of cooling garments [226]. Conventional evaporative cooling garments take advantage of the high latent heat of water evaporation and provide a cooling effect by facilitating evaporation through a highly absorbent fabric structure [241,[281][282][283], as shown in Figure 8. Then, the cooling effect lasts until all the moisture in the cooling garment evaporates.…”

The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and therefore may be more exposed to accidents and injuries. Due to the incompatibility of the existing standards implemented in some workplaces and the lack of thermoregulation in many types of protective equipment that are commonly fabricated using various types of polymeric materials, thermal stress remains one of the most frequent physical hazards in many work sectors. However, many of these problems can be overcome with the use of smart textile technologies that enable intelligent thermoregulation in personal protective equipment. Being based on conductive and functional polymeric materials, smart textiles can detect many external stimuli and react to them. Interconnected sensors and actuators that interact and react to existing risks can provide the wearer with increased safety, protection, and comfort. Thus, the skills of smart protective equipment can contribute to the reduction of errors and the number and severity of accidents in the workplace and thus promote improved performance, efficiency, and productivity. This review provides an overview and opinions of authors on the current state of knowledge on these types of technologies by reviewing and discussing the state of the art of commercially available systems and the advances made in previous research works.

“…Fuzzy PID control has been widely used for industrial processes owing to its heuristic nature associated with simplicity and effectiveness for linear and nonlinear systems. Since the method is robust and proven in many fields, it has been applied to various aerospace systems [30][31][32]. However, it is hard to find research related to the nonlinear control algorithm for VTSRM and its performance.…”

This paper deals with a performance comparison of the control algorithm for a variable-thrust solid-propellant rocket motor (VTSRM). To do this, we develop a simulation model of a VTSRM considering characteristic changes in the combustor and design control systems for pressure and thrust. We use three types of control algorithms for the pressure control: classical PID control, feedback linearization control, and fuzzy PID control, and two control algorithms for thrust control: classical PID control and fuzzy PID control. Finally, we compare the performance of each control system through a numerical simulation using step responses. Through this work, we check that feedback linearization is better in pressure control, and fuzzy PID control is more appropriate in thrust control. Especially using fuzzy PID control, we can get fast settling with a small undershoot even if the system is a nonminimum phase system.
