An adaptive dual controller for a MIMO-ARMA system

An adaptive dual controller is presented here for a multi-input multi-output system. The plant has constant but unknown parameters. The cautious and a new dual controller are examined. In many instances, the cautious controller is seen to turn off. The dual controller modifies the cautious control design by numerator and denominator correction terms which depend upon the sensitivity functions of the expected future cost and avoids the turn-off and slow convergence. Monte Carlo comparisons based on parametric and nonparametric statistical analysis indicate the superiority of the dual controller over the cautious controller.
