The solution is based on a generalization of the Hermite-Biehler theorem applicable to polynomials with complex coefficients and the application of a modified stabilizing gain algorithm to three subsidiary plants. The method given is also applicable to PID controllers.EnglishStabilizationFirst-order controllersRegional pole placementHermite–Biehler theoremArticle10.2316/Journal.201.2009.1.201-20301925-5810
