Zusammenfassung
This paper makes a study of LTR (Loop Transfer Recovery) desing methods. the applicability of the methods to a multivariable system is demonstrated. State space methodos are used to implement the control algorithms and frecuency domain techniques are used to analyse its robutstness. Robustness indicators are proposed to evaluate the performance of the controllers. Different designs of a multivariable system are made, and the results obtained by a conventional LQG/LTR controller and a LTR controller without observer are compared. Finally a method is proposed to enhance the robustness and applicability of conventional LQG/LTR controllers.
