Dynamics of a class of uncertain nonlinear systems under flow-invariance constraints.
Time-domain and parametric -properties corresponding to Popov inequality
For Popov’s frequency-domain inequality a general solution is constructed in , which relies on the strict positive realness of a generating function. This solution allows revealing time-domain properties, equivalent to the fulfilment of Popov’s inequality in the frequency-domain. Particular aspects occurring in the dynamics of the linear subsystem involved in Popov’s inequality are further explored for step response, as representing a usual characterization in control system analysis. It is also...
