Peritoneal Carcinomatosis (PC) is an abdominal cancer for which cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (HIPEC) proved to be a promising treatment. HIPEC requires the intraperitoneal spread of cytostatic solution at high temperatures (41-43˚C) accomplished within 60-120 minutes, during surgical interventions. This paper presents the heating system's identification, by using a graphical fitting method on a temperature measured signal, for a HIPEC device intended to be developed. Also the design of two PID temperature controllers is presented, using the Strejc design method and the Ziegler-Nichols method. The two feedback control structures are compared via simulation, based on their step response signals and their overall performances.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
