TY - JOUR T1 - FAST CALCULATION OF ALL STABILIZING GAINS FOR DISCRETE-TIME SYSTEMS AU - Bayhan, Nevra AU - Söylemez, Mehmet Turan PY - 2012 DA - January JF - IU-Journal of Electrical & Electronics Engineering PB - İstanbul University-Cerrahpasa WT - DergiPark SN - 1303-0914 SP - 19 EP - 26 VL - 6 IS - 1 LA - en AB - In this paper, two methods for calculating all stabilizing gains for discrete-time systems are given. The first method focuses on converting the problem using a bilinear transformation and then applying a previously developed theorem for continuous time systems. Unlike previous results, the method introduced here does not use the Generalised Hermite-Biehler Theorem and therefore provides a computational advantage. The second method demonstrates the use of Chebyshev Polynomials in the solution of the problem KW - Bilinear Transformation KW - Nyquist’s Criterion KW - Chebyshev Polynomials CR - Ackermann, J., Kaesbauer, D., Bajcinca, N., “Discrete-Time Robust PID And Three Term Control”, XV IFAC World Congress, Barcelona, Datta, A., Ho, M.T., Bhattacharyya S.P., Structure and Synthesis of PID Controllers, Springer, London, UK, 2000.
