Economic sensor/actuator selection and its application to flexible structure control

摘要

A systematic design method is proposed for the selecting of actuators and sensors in the structural control in order to minimize the instrumental cost. With actuators and sensors placed at all the admissible locations initially, an iterative minimization algorithm is carried out to identify the sensor/actuator that requires the least precision. By deleting the roughest sensor/actuator each time till loss of feasibility, one can conclude simultaneously the necessary number and type of sensor/actuator, and the location and precision for each sensor/actuator. A tensegrity structure example has been solved as an application of the proposed algorithm.
