N2 - Nominal precision of state observation and bandwidth of sliding mode (SM) observers are analyzed through the frequency-domain method. The previously developed approach to analysis of SM observers as relay feedback-feedforward systems is used and further extended to analysis of effects of design parameter change on observer performance. An example of SM observer design for estimation of DC motor speed from the measurements of armature current is considered in the paper. The input-output properties of observer dynamics are analyzed with the use of the Locus of a Perturbed Relay System (LPRS) method.
