# ELE 302 Lecture Notes - Lecture 7: Step Response, Damping Ratio, Settling Time

## Document Summary

Based on the information in the previous item, build and appropriate second order model for the system with such step response as shown. 7. 3. 5 example consider a certain closed loop control system described by the following transfer function: 7. 3. 6 example consider a certain closed loop control system described by the following transfer function: Estimate transient response specifications (po, trise10% 90% , and. Consider a response of a certain closed loop control system to a unit reference signal, as shown. Based on the graph, determine the following step response specifications: percent overshoot (po), settling time ( % ), ( % ), rise time ( % % ), period of oscillations ( ), and frequency of damped oscillations ( ), as well as the steady state error ( %). Next, based on the information collected, determine an appropriate 2nd order model for the closed loop system in question. Constants and steady state errors for the ramp and parabolic inputs.
