Abstract
For an adaptive structure there are two critical design components: temporal compensation and spatial compensation. The influence of the controller on the sensor signals characterizes the temporal compensation of the adaptive structure and the dynamic coupling of the actuator and sensor through the structure characterizes the spatial compensation. Traditionally, techniques for adaptive structure design have concentrated on one component and considered the other fixed. This work proposes a method of concurrent design for both the temporal and spatial compensation of an adaptive structure. Concurrent design concepts are realized by simultaneously executing controller optimization and spatial optimization routines. The structural acoustic control performance and robustness of an adaptive plate structure is improved significantly with concurrent design. The results show the advantages of concurrent design concepts over traditional methods and the effectiveness of the proposed approach.
