Servo compensation for mechanical resonances and feedback loops.

When the transfer function of a system has at least one pair of complex poles, resonant peaks will occur in the open-loop frequency response at the frequency determined by these complex poles, The resonant peaks may produce instability in the closed-loop system. Cascaded complex-zero compensators are studied in order to cancel the effect produced by the complex poles. Circles of stability are developed and if the complex zeros of the compensator are located inside the circles the system stability is guaranteed. Several locations for the complex zeros in the s-plane are studied and a correlation among frequency-response, transient-response and root-locus techniques is described to aid in the design of the compensator. (Complex poles are often generated by mechanical resonances)
