PART 1
1.1 Draw a block diagram for the control system generated when a human being steers an automobile.

1.2 From the given figure specify the devices

Solution:

Inversion by partial fractions:

3.1(a)

dx 2 dx + + x = 1 x ( 0) = x ` ( 0) = 0 2 dt dt

? dx 2 ? L ? 2 ? = s 2 X ( s ) ? sx(0) ? x ` (0) ? dt ?

? dx ? L ? ? = s X ( s ) ? x ( 0) ? dt ? L(x) = X(s)

L{1} = 1/s
s 2 X ( s ) ? sx(0) ? x ` (0) + s X ( s ) ? x (0) + X ( s ) =
1 s 1 s

= ( s 2 + s + 1) X ( s ) = 1 s( s + s + 1)
2

X ( s) =

Now, applying partial frac
