Frequency-domain conditions are derived for characterizing parameters of output dynamic controllers providing absolute stability and a relavant performance for various classes uncertain systems, such as nonlinear Lur’e systems, systems switched by an unknown law, linear systems with time-varying norm bounded parameters and some others.
Keywords: absolute stability, minimax techniques, output dynamic controllers, frequency-dependent characteristics
