Abstract
Given a multivariable plant with uncertain or unknown dynamics, the use of step response data in control design is described based upon a simple diagonal model of a precompensated plant. The technique is identical in structure to the inverse Nyquist array design technique with Gershgorin circles replaced by "confidence circles" deduced from simple graphical operations on plant step data.
