AUTONOMOUS HUMAN BODY CONTROL, PART XIII: SERUM MAGNESIUM CONTROL USING I-FIRST ORDER AND I-SECOND ORDER COMPENSATORS COMPARED WITH PI CONTROLLER

This paper is the thirteenth in a series of research papers presenting the autonomous control of the human body. It handles the control of serum magnesium concentration using I-first order and I-second order compensators from the second generation of control compensators. The proposed compensators are tuned using multiple approaches including zero/pole cancellation, specific performance characteristics fulfillment and trial and error. The step time response of the control system using the two proposed compensators is presented and compared with using a PI controller from the first generation of PID controllers to control the same patient dynamic characteristics of serum magnesium concentration and the time-based characteristics are compared. The comparison reveals the best controller among the three compensators/controller depending on a graphical and quantitative comparison study.
