PID controllers consist of Proportional, Integral, and
Derivative blocks that manipulate the error of the Process Variable
signal depending on their own characteristics. Some controllers use
these three blocks while some other controllers use the P block or
the P block in conjunction with another one. In any case, the P
block seems to be always present.
Discuss if we can have controllers that employ only an I block
or a D block alone.
Describe why or why not using...

catalyst(s), solvent(s), resonance structure(s) of transition
state(s), product(s) etc.

Design a digital PID controller based on the Ziegler_Nichols
method for for the following system:
G(s)=s/((s+1)^4 )
use the sampling time of T=0.1 seconds and simulate the
resulting controlled system by applying a unit
step and then changing the value of input to another value after
some appropriate time
Discus the effect of set point change.
