Jean-Pierre Corriou, in Coulson and Richardson's Chemical Engineering (Fourth Edition), 2017. Linear quadratic Gaussian control of a chemical reactor. The same chemical reactor as for LQ control is used to evaluate LQG control. The same set points are imposed. In this case the theoretical states describe the behavior of the plant but noisy measurements are used as process outputs.

Residence time - Wikipedia

History. The concept of residence time originated in models of chemical reactors. The first such model was an axial dispersion model by Irving Langmuir in 1908. This received little attention for 45 years; other models were developed such as the plug flow reactor model and the continuous stirred-tank reactor, and the concept of a washout function (representing the response to a sudden change .
