Abstract: The regularities of motion of a point on the plane (in the space) of adjustable controller parameters at variations of the phase margin under a fixed crossover frequency were analyzed. The problem of decomposition of the stability domain into the zones with simple and complex Nyquist plots and subsequent construction of the point subset where all points satisfying the requirements on the system frequency characteristics was solved. Examples were presented.
