Block Diagram From Transfer Function. Find the transfer function of the system described by the equation d2 y 3dy 2y u where ut is the input and yt is the output. A block diagram can be used simply to represent the composition and interconnection of a system.
Taking laplace transform both sides with zero initial conditions we obtain s2 3s 2ys us hence 1 2 1 q s s s h s g s 25 block diagrams block diagrams the equationys gsus is represented by the fig27 gs. Therefore the transfer function is w 1 w 2. Getting transfer function from block diagramhelpful.
Step 2 repeat step 1 for remaining inputs.
This relates the input θi and output θo. By equation 73 the output c due to input u is c g21 g1g2u. Feed forward transfer function 3. A block diagram can be used simply to represent the composition and interconnection of a system.
