Most published “interaction measures” can produce misleading results and often do not measure the true closed‐loop interaction. Therefore, closed‐loop transmittances are defined mathematically as direct, parallel, disturbance , and interaction transfer functions and it is shown that the direct Nyquist array design method includes an excellent basis for interaction analysis.
