Small phase theorem
Webproposed nonlinear system phase, serving as a counterpart of L 2-gain, quanti es the passivity and is highly related to the dissipativity. A nonlinear small phase theorem is then established for feedback stability analysis of semi-sectorial systems. It generalizes a version of the passivity theorem and the linear time-invariant small phase theorem. Webin the phase concept. While the small gain theorem is widely known in the field of robust control, much less attention has been paid to the development of a small phase theorem. Moreover, the magnitude plot of a MIMO frequency response has been inbuilt to the computing environment MATLAB, a useful phase plot has not been available in practice ...
