The closed-loop properties are discussed. The weighting matrices of a quadratic performance index are related to the closed-loop pole-zeroes so that the weighting matrices can be selected on-line according to the locations of the desired closed-loop poles. Simulation results illustrate the good performace and reliability of the controller.
