Shape memory alloy (SMA) has been utilized as the material of smart actuators due to miniaturization and lightweight. However, nonlinearity hysteresis SMA seriously affect precise control. In this article, a novel disturbance compensation-based adaptive control scheme is developed improve performance actuator system. Firstly, nominal model constructed based on physical process. Next, an estimat...

Lightweight structures capable of changing their shape on demand are of interest for a number of applications, including aerospace, power generation, and undersea vehicles. This paper describes a bioinspired cellular metal vertebrate structure which relies on shape memory alloy (SMA) faces to achieve fully reversing shape change. The resulting vertebrate actuators can be combined with flexible ...

Currently, when direct human contact is limited owing to the coronavirus era, virtual reality systems are a technology that enables interaction without spatial restrictions. In this study, system capable of feedbacking various shapes and stiffness touching an object in was conceived using SMA textile actuator, which shape memory alloy (SMA) remembers by training at 500 °C for 15 min with tools ...
