BLOCK DIAGRAMS REDUCTION
It is a representation of the control system giving the inter-relation between the transfer function of various components. The block diagram is obtained after obtaining the differential equation & Transfer function of all components of a control system. The arrow head pointing towards the block indicates the i/p & pointing away from the block indicates the o/p.
If G(s) is TF, G(S)= C(S)/R(S)After obtaining the block diagram for each & every component, all blocks are combined to obtain a complete representation. It is then reduced to a simple form with the help of block diagram algebra.
The following block diagram reduction algebra is used,when
1.Block in cascade (series)
2. Combining blocks in parallel
3. Eliminating a feed back loop
4. Moving a take-off point beyond a block
5. Moving a take-off point ahead of a block
