An introduction to control using state variable system models

Abstract

State space system models are popular because of the precision they bring to the task of modelling systems or processes we wish to control. Simulink and other simulation software tools usually have a state variable system icon or routine to help us exploit the structure and notation when we wish to load the state variable matrices A, B, C, D with system data. The very fact that we describe a system using a state variable equation model leads directly to new terms and analysis methods when we discuss system stability and system responses.
