Abstract: It is required to determine the phase coordinates of a nonlinear dynamic plant and the measurement system. This can be done by nonlinear filtering with plant equation and the measurement system linearized with respect to the measured values of phase coordinates. Formulae are given which make it possible to design a filter for detection of phase coordinates. An example illustrates the use of the method.
