The Control System Toolbox is a collection of functions for the modeling, analysis, and design of automatic control systems. It provides classical tools such as Bode plots, Nichols plots, or root locus, as well as modern techniques such as state-space LQG or pole placement design.

Custom data structures allow for compact representation and easy manipulation of LTI models. The Toolbox contains functions to analyze model dynamics (poles, zeros, gain), plot time and frequency responses, discretize models, connect systems together, and design static or dynamic feedback compensators.
