An approach is presented for pole placement in controllers and observers. The first-order perturbation of the system eigensolution is used to analyze and design the feedback gains. The accuracy of the control (or observer) design depends on how small a perturbation the control gains are on the uncontrolled system, and it is assessed qualitatively and quantitatively.
