Modeling and control of piezo actuated structures with uncertainties using interval arithmetic approach

Abstract

The development in piezoelectric materials has accelerated the newlineresearch in the field of smart structures A smart structure can be defined as newlinethe structure that can sense external disturbance and respond to that with newlineactive control in real time to maintain the mission requirements Smart newlinestructures consist of highly distributed active devices which are primarily newlinesensors and actuators either embedded or attached to an existing passive newlinestructure with integrated processing networks newlineThe active vibration control of smart structures that inherently have newlineflexibility becomes more important when the designers attempt to push with newlinethe state of the art faster and lighter structures for space applications newlineGenerally two steps are necessary for the control of flexible smart structures newlineFirst a precise mathematical model which is capable of handling the newlineelectromechanical coupling effects must be developed newline newline
