Most physical systems are nonlinear to some extent. One variety of nonlinear system uses a relay or other on-off device as a control element . Since in the process industries or relay servo systems, one often encounters a type of time delay called transportation lag or dead time. It is highly desirable to investigate the effects of the transportation lag on the process or relay servo system.
