Unformatted text preview: stability is that all of the coefficients must have the same sign. Since only positive values for K are considered, the closed–loop system is stable for K > 0. The closed–loop system is overdamped for all K . The 2% settling time decreases as K increases and approaches 4/4 s as K approaches ∞. For r ( t ) = 5, Compensators The steady state output is 4.46. The 2% bounds for the output are 4.37 and 4.55. The output reaches 4.37 and stays within the bounds at 0.412 s. Therefore, the graphically determined 2% settling time is 0.412 s. The percent overshoot is 0% since the response is overdamped.
