CONTROL SYSTEMS

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

    i want solved complicated questions on the topic block diagram reduction,questions based on to shift summing point before n after takeoff point

  8. anusha says:

    i need to know why a system acts as bounded for some inputs unbounded for someother. do stability depend on nature of input applied?
