What is a second order system
|
One whose output is described by the solution of a second order differential equation
|
|
|
What are the 3 types of second order systems and thier characteristics
|
Overdamped zeta > 1, as zeta increases, response is slower.
Critically damped: zeta = 1, fastest response without overshoot Underdamped: zeta between 0 and 1, as zeta approaches 0, response has a higher degree of overshoot and oscillation |

Describe the following:
Rise Time Time to First Peak Settling TIme Overshoot Decay Ratio Period of oscillation |
Tr, TIme taken to reach the set point (steady state value) get using formula or graph
Tp, Time at which first peak occurs Ts, Time to reach and remain inside a band of less than 5% change OS = part above graph/part below graph (a/b) DR = c/a P= time between two peaks |
