Fractional-order PD control design for active vibration control of smart structures
Апстракт
Smart structures are obtained by integration of actuators, sensors and controllers into conventional structures
and they play an important role in the field of active vibration control, especially in aerospace engineering.
Certain elements of a smart structure possess viscoelastic properties which can be modeled by using fractional
calculus. The fractional-order model of a smart structure implies the necessity of using fractional order
controllers instead of integer order controllers. This paper deals with design of the fractional-order proportionalderivative
(PD) controller with robust stability and disturbance rejection. The transfer function of the fractionalorder
PD controller is parameterized, and these parameters are found by using of the Particle swarm
optimization method minimizing a cost function related to the H����� norm. The fractional-order model of the smart
structure is found by experimental identification by using the frequency response method. In order to repre...sent
the efficiency of the proposed controller, obtained results are compared with the corresponding results in the
case when an integer-order PD controller is applied.
