Abstract

Abstract: The parameter optimization method for multivariable systems is extended to the controller design problems for multiple input multiple output (MIMO) square fractional-order plants. The algorithm can be applied to search for the optimal parameters of integer-order controllers for fractional-order plants with or without time delays. Two examples are given to present the controller design procedures for MIMO fractional-order systems. Simulation studies show that the integer-order controllers designed are robust to plant gain variations. Abstract : Highlights: Extend a parameter optimization method to controller design problems for MIMO FO-plants. The methodology can be applied to fractional-order plants with or without time delays. The robustness tests show that the controller is robust to the plant gain variations.
