DPS Blockset Demo Heated metal body
The metal body heating with four heating elements is modeled by lumped-input / distrinuted-output system. System dynamics is given by finite elements method numerical structures of metal body , corresponding to parabolic type partial differential equation and transfer functions of heating elements:
,
and
, where
is shaping unit of i-th distributed input quantity (i=1-4).
