Integrated thin film-based shape memory polyimide composites (SMPICs) are potentially attractive for efficient and compact design, thereby offering cost-effective applications. The objective of this article is to design and evaluate a mirror manipulator using an SMPIC as an actuator and a sensor with control. A sensor-less control strategy using the SMPIC (a self-sensing actuator) with a proportional derivative combined variable structure controller (PD-VSC) is proposed for position control of the mirror in both the vertical and angular directions. The mirror manipulator is able to move the mirror in the vertical and angular directions by 3.39 mm and 10.5 deg, respectively. A desired fast response is obtained as the performance under control. In addition, some benefits from the proposed control realization include good tracking, stable switching, no overshoot, no steady state oscillations, and robust disturbance rejection. These superior properties are experimentally validated to reflect practical feasibility.
集成薄膜基形状记忆聚酰亚胺复合材料(SMPICs)对于高效紧凑设计具有潜在吸引力,从而提供具有成本效益的应用。本文的目的是设计并评估一种使用SMPIC作为致动器和带有控制的传感器的镜面操纵器。提出了一种使用SMPIC(自传感致动器)与比例微分组合变结构控制器(PD-VSC)的无传感器控制策略,用于镜面在垂直和角度方向上的位置控制。该镜面操纵器能够使镜面在垂直和角度方向上分别移动3.39毫米和10.5度。作为控制下的性能,获得了期望的快速响应。此外,所提出的控制实现带来的一些好处包括良好的跟踪、稳定的切换、无超调、无稳态振荡以及强大的抗干扰能力。这些优异特性通过实验验证以反映实际可行性。
