dc.description.abstractThis thesis is concerned with the application of a method for control system design based on Youla(Q)-Parametrization. The fundamental concepts of the parametrization method have been used by Newton et al, Franklin and Raggazzini [Maciejewski, 1989] as early as 1957. The importance of its implications were not noticed during those years, but Youla and Kucera renewed it in the seventies [Maciejewski, 1989]. For the special case of an open loop stable plant, the implementation can be realized in the Internal Model Control(IMC)-Structure [Morari, 1987]. The IMC-Structure is essentially a open loop design method for closed loop controllers, thereby simplifying the design procedure. A Multivariable controller design method is proposed that unifies the advantages offered by three design approaches/techniques, namely, The Q-Parametrization, The IMC-Structure and The Characteristic Loci Technique. The proposed method is based on controller parametrization. In addition, it retains the engineering insight and simplicity of the IMC-Structure. This is particularly useful in solving complex multivariable problems. The design method was evaluated by its application to the design of a control law for a FLOTATION PROCESS SIMULATOR RIG(FLOTRIG) built by Mr Fisher[Fisher, 1988]. The design of the Multivariable controller was based on a Transfer Function Matrix, G(s), which is a Linear Time Invariant(LTI) model of the FLOTRIG.en_ZA
