... 1 974 ), and recursive algorithms for adaptive control (Cypkin, 1 971 ). The above given survey of development in automatic control also influenced development in process control. Before 1940, processes ... automatic control as the capacities were larger and the demand of quality increased. The controllers used did not consider the complexity and dynamics of controlled processes. In 1...
