Frequency domain specifications
resonant peak Mr is the maximum value of jM(jw)j.
frequency !r is the frequency at which the peak resonance Mr occurs.
bandwidth BW is the frequency at which(jw) drops to 70:7% (3 dB) of its
indicates the relative stability of a stable closed loop system.
Mr corresponds to larger maximum overshoot of the step response. Desirable
value: 1.1 to 1.5
an indication of the transient response properties of a control system.
bandwidth corresponds to a faster rise time. BW and rise time tr are inversely
indicates the noise-filtering characteristics and robustness of the system.
Increasing wn increases BW.
BW and Mr
are proportional to each other.
