Process which is serially connected with interacting linear lags in many stages is frequently seen in actual process control system. This paper presents the relations between dead time and dead zone to stabilize the system which consists of three position relay element, dead time and serially connected two stage process with interacting linear lags. Frequency response of the system is also investigated. Validity of the above analysis is proved through experiments on the practical system which employs a sinusoidal signal generator of pneumatic pressure by relay servo.
