Integrated Design of Actuator for Thin Plate Optical Reflector
摘要
Abstract
Integrated design of an actuator for the thin plate optical reflector is conducted in this paper. Due to the particularity of the thermal flutter of the solar array, a finite element model is established to analyze dynamic responses, based on which, a magnetostrictive actuator(GMM)is proposed for performing surface deformation compensation. In addition, the dynamic model of the actuator is established and the performance is discussed by using the fuzzy adaptive PID algorithm. The results show that the proposed actuator can achieve a large stroke, higher positioning accuracy, and can be used for surface deformation compensation.关键词
