Non-smooth nonlinearities have a significant influence within many power system controllers, and hence affect overall system dynamic behaviour. This paper focusses on the output limiters of power system stabilizers (PSSs). Even though these limits play an important role in the response of generators to large disturbances, only ad hoc tuning procedures have been available. Therefore a systematic...
