Please modify your question and choose a different example. A good choice is the temperature controller for your frying pan (in the kitchen). | |

The systems on which control theory can be applied are virtually limitless and span almost any discipline you can imagine. From physics to chemistry and biology to economics, it's much more than gears, motors and electronics. Much more than inputs, outputs, poles and zeros. | |

If the input is text and the output is the same text delayed by T secs then the transfer function is a pure time delay, e^-sT. Same procedure with any system, but determining the I/O relationship is not always so simple. | |

| Mar 16, 2015 at 19:45 | comment | added | Andy aka | The "most real life example" is only valid until a better one comes up and this means there is no best answer to this and answers will tend to become out of date. Now how about you think of a decent proposal for a system - maybe a motor that turns to a preset position following a demand from a potentiometer? | |

| Mar 16, 2015 at 19:30 | comment | added | Samuel | Your model is terrible. How do you find the transfer function of a human life? You need to start with a system where the inputs and outputs are known, then you can do math on it. | |
| Mar 16, 2015 at 19:28 | comment | added | Jeff Wurz | You are trying to model so many systems if you think about just the cell phone... when each component is designed this is done, but not the whole phone. | |
