Reference Model Robust Control of ΜIMO Systems with an Incomplete Access to the State Variables

Abstract

A control structure for control of systems with an indirect access to some state variable is presented. The method is based on a control structure with an adaptive reference model. Whilе thе base control structure is sensitive to non-measurable disturbances the control task is divided between the controlled systm and reference model. The model is completed by a controller and feedback. This arrangent enables to keep the steady-state also when diturbances occur. An illustrative example of the controllers design for two-motor drive system demonstrates the main results. A general access to the solutuon enables to widen the proposed control structure to other multivariable systems.
