| Dec 5, 2016 at 21:50 | comment | added | Petrus | Both in electronics and in control theory, the poles of the final transfer function determine the stability of the system. If they are all on the left half-plane the system is stable. It is a property of the system and does not depend on the inputs. This may be applied to any system (hence, also those including OpAmps). | |

| Dec 5, 2016 at 9:05 | comment | added | Andy aka | An op-amp IS a control system and subject to control theory therefore, your question becomes redundant because you are considering that an op-amp doesn't wholly fall under the mathematical umbrella of control theory. | |

| Dec 5, 2016 at 7:41 | comment | added | emnha | In control theory, stability is defined as a measure of the tendency of a system's response to return to zero after being disturbed. So does the definition is also applied in electronics (for example OpAmp) and how to test it (say OpAmp) using this definition? | |
| Dec 5, 2016 at 7:25 | comment | added | Chu | Stability and relative stability mean the same in all fields. The method of assessing it can vary. | |
| Dec 5, 2016 at 3:52 | comment | added | user57037 | In electronics, a system may be considered only marginally stable if the step response has overshoot. I think this is why it is considered desirable to have sizeable margins. | |
