[edit intro]

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[edit]

Control design methods which are considered to belong to the class of classical control include:

Root locus method

Quantitative feedback theory

The Guillemin-Truxal method

Lead, lag and lead-lag compensation
