A method for performing system characterization in situ for a system comprising a actuator controlled by a proportional controller. The system includes a quasi-linear region characterized by a slope of the system response and by a delay in the quasi-linear region of the system. The system includes at least one dead zone (DZ). The method comprises the following steps: (A) applying an input waveform U(t) to an input of the system comprising the actuator controlled by the proportional controller; (B) measuring waveform characteristics of an output waveform {dot over (X)}(t) in a relevant region of the output waveform; (C) calculating a set of parameters selected from the group consisting of: {at least one DZ; a system delay; and a slope of the system response in the quasi-linear region of said system} based on the measured waveform characteristics of the output waveform; and (D) performing the system characterization in situ by using the set of calculated parameters selected from the group consisting of: {at least one DZ; the system delay; and the slope of the system response in the quasi-linear region of the system}.
