Abstract

In using control with state vector feedback in process control certain difficulties arise. However they can be avoided for the most part if the controller with state vector feedback is used within the special two-level control structure proposed in this paper. The philosophy of the structure is to consider all known properties-structure, parameters and measurable disturbances-of the plant within an open-loop, feed-forward, upper level control scheme containing a model of the plant to be controlled and a controller which feeds back the model's state vector. Then a feedback servo system at the lower level has only to compensate for small deviations between the plant's model and the real plant caused by unknown or unregarded properties of the plant. A final example shows the application of the structure to the power control of a steam cooled fast reactor simulated on a hybrial computer.
