DPS Blockset Demo String of "smart" structure
The string of "smart" structure deviation by means of piezoceramic actuators is modeled by lumped-input / distrinuted-output system. System dynamics is given by distributed transfer function of oscillating string , corresponding to hyperbolic type partial differential equation and transfer functions of piezoceramic actuators:
,
and
, where
is shaping unit of i-th distributed input quantity (i=1-4).
