Control system notes rgpv

From these responses, we can conclude that the first order control systems are not stable with the ramp and parabolic inputs because these responses go on increasing even at infinite amount of time

The first order control systems are stable with impulse and step inputs because these responses have bounded output

In the earlier chapters, we have discussed two mathematical models of the control systems

Those are the differential equation model and the transfer function model

The state space model can be obtained from any one of these two mathematical models

Let us now discuss these two methods one by one
