Quasipolynomial approach to simultaneous robust control of time-delay systemsSemenič, Nikolaj (Avtor) Sarjaš, Andrej (Avtor) Chowdhury, Amor (Avtor) Svečko, Rajko (Avtor) time-delay systemssimultaneous robust controlalgorithmA control law for retarded time-delay systems is considered, concerning infinite closed-loop spectrum assignment. An algebraic method for spectrum assignment is presented with a unique optimization algorithm for minimization of spectral abscissa and effective shaping of the chains of infinitely many closed-loop poles. Uncertainty of plant delays of a certain structure is considered in a sense of a robust simultaneous stabilization. Robust performance is achieved using mixed sensitivity design, which is incorporated into the addressed control law.02017-06-15 08:47:47Znanstveno delo66213sl
