摘要

本文讨论了由位置相关热负荷引起的热致变形的建模和控制问题。采用谱法和有限元相结合的方法对这些变形进行了建模。对于这种类型的系统，提出了一种分布式前馈控制器，该控制器仅在热负荷的位置附近起作用。结果表明，该控制器显著降低了柔性梁的热致变形。

Modeling and localized feedforward control of thermal deformations induced by a moving heat load

This paper deals with the modeling and control of thermal induced deformations that are the result of a position dependent heat load. These deformations are modeled using a combination of spectral methods and FEM. For systems of this type, a distributed feedforward controller is proposed that acts only around the location of the heat load. The results of this controller show a significant reduction of thermal induced deformations of a flexible beam.
