トラス構造物の静的形状制御のためのアクチュエータ・センサ配置(機械力学,計測,自動制御)

This paper shows an optimal placement of actuators/sensors for static shape control of truss structures with partial measurements. The location of the actuators/sensors is determined by the genetic algorithm in order to minimize the objective functions that are related to control effects for actuators and estimation errors for sensors, respectively. Unmeasured shape is estimated with a modal expansion method. An example of an antenna truss is discussed to assess the performance of the present static shape control. It is shown that the present placement method for actuators and sensors are effective for the control of truss structures.
