Method of controlling photographic emulsion manufacturing process by non-linear approximation
 A method of controlling a photographic emulsion manufacturing process by non-linear approximation, wherein the set of (k) of a plurality of process inputs, the set (k) of a plurality of states, such as the silver halide concentration, the set (k) of a plurality of process outputs, such as the potential of silver and the pH value, and an evaluation function J (k) are defined, so that a feedback matrix .sub.b (k) and a feed-forward control matrix .sub.f (k) which minimize said evaluation function J (k) are obtained and that manipulated variables which are to be applied to a plant is calculated from the obtained feedback matrix .phi..sub.b (k) and feed-forward matrix .sub.f (k).
