Control Structures Based on Constrained Inverses

Abstract

Present paper proposes a well structured control solution for the local control level allowing the integration of different types of engineering information into the control algorithm. Based on a comparative study of the structures of PID and IMC controllers a novel control structure with two degrees of freedom (or three if the possibility of adaptation is considered too) is defined. The application of the new control structure is illustrated by the example of the temperature control in a laboratory water heater system.
