Abstract
Abstract A control arrangement for processes involving a plurality of control variables and an output variable depending in a complex manner on the various control variables wherein the deviation between the output vectors of a reference model and of the process is employed and on the basis of this deviation the synthesis of the control vector is formed so that the output variables of the process will follow the output variables of the reference model without it being necessary to know the relationships between the input variables and the output variables.
