Classical control
From Citizendium, the Citizens' Compendium
In control engineering, the term classical control often refers to control methodologies developed prior to the advent of state space methods (which collectively go under the heading of modern control theory) in the 1960's due to the influential works of Rudolf E. Kalman. The methods of classical control rely heavily on complex analysis and transform methods, especially the Laplace and Fourier transforms, as well as graphical techniques.
Classical control methods
Control design methods which are considered to belong to the class of classical control include:
Lead, lag and lead-lag compensation
