Compensators (Dorf & Bishop)

Compensators (Dorf & Bishop). Compensator is a first order network with the transfer function: If then it is called a phase-lead compensator, otherwise it is called a phase-lag compensator. The maximum phase contribution (lead or lag) occurs at the frequency:

Digital Control

Digital Control. The s plane root locus design technique concentrates on two figures of merit: time to peak and percent overshoot. From these two figures of merit we determine values for the damping ratio and natural frequency. ( See equations 5.14 and 5.16 )
