ABSTRACT

Physiological control systems are a field of study of regulatory process that

contribute to natural operating characteristics of biological systems. In order to attain

that understanding, the project explains how the methodology of control modeling is

applied to engineering control systems that can be extended to physiological control

systems. Bio-Medical Instrumentation is an expanding and demanding area in which

many fields are available to explore, among which diabetes is a main segment to

address.

Here we develop a automatic respiratory control for a normal person .In order

to develop this we first derive mathematical model and simulate it to get values at

steady state point which act as controller set point and is given to a control valve. so

that we can regulate the breathing.
