Objective:

  1. Introduction to second order system
  2. To determine the response c(t) of a system for a unit step input

r(t) =1.0 and display the same in time domain graphically

3.To determine various criteria of time response such is

undamped natural frequency , damping ratio, frequency of

damped oscillation , peak overshoot. time to reach peak over

Theory:

In the speed control system, the plant characterized by its time constant,

which is determined by the inertia of the rotor and the viscous friction.

This arrangement can be described mathematically by a first order

differential equation.

The position control system has an integration effect between velocity

and position. This makes the position control servomechanism into a

second order system.

Circuit diagram:

The transfer function of the circuit above is given below:

(where output is taken across the capacitor)
