Elements of Control Systems Response Characteristics Amplitude Input Command Overshoot Transient Response Settling time, ts, is the time it takes output to settle within a specified boundary typically 2%). Rise time, tr, is the time it takes for the output to change from 10% to 90% of final value. Peak time, tp, is the time to reach the vicinity of set point, and usually the largest, peak. Overshoot, Mp, is the amount that the peak exceeds the steady state value at the peak time. generally expressed as a percentage of the final steady state value. Time Steady State Response Steady State Error 24
Elements of Control Systems Response Characteristics • Stability is defined as the ability of a control system to achieve its goal without going into oscillation. • The total response of a control system is a combination of the natural response, totally governed by the plant, and the forced response, typically governed by the controller. • It is a mandatory requirement that a control system be stable. 25
