摘　　要：本文研究了热压电仿生热鲁棒结构中致动器配置的优化问题。首先分析了热压电弹性介质的动态控制方程，讨论了各耦合因素对仿生热鲁棒结构控制的影响及致动器的工作机理。在该基础上，提出目标函数来评价系统可控性以优化致动器的放置，并用具体算例讨论了热压电致动器在梁上配置对模态可控度的影响，得到了有关致动器配置的结论。The actuator placement optimization of piezothermoelectric biotic thermal robust structure is studied in this paper.The governing equations for piezothermoelasticity continuum are presented first and the effects of coupling factors on the control of biotic thermal robust structure and the work mechanism of actuator is discussed later.Based on those analyses,objective functions are presented to evaluate the system controllability and so actuator placement optimization studies can be conducted.And the effects of placement optimization of piezothermoelectric actuators on the degree of modal controllability are illustrated by numerical examples.According to the results of the optimal analysis procedure of actuator placement,some conclusions of actuator placement are achieved.
