Is a positive PI (proportional and integral) controller (plus unit negative feedback) able to control your plant?

Question

Accepted Answer

No, the resulting control system T(s) would be unstable for every gain

Answer

No, the controller C(s) would be non-causal

Answer

Partially, the complete control system T(s) is stable and precise to step, but the system is both too slow and too oscillatory (or with too much overshoot)

Answer

Partially, the complete control system T(s) is stable and precise to step, but the system is too oscillatory (or with too much overshoot)

Answer

No, the controller C(s) would be unstable

Answer

Partially, the complete control system T(s) is stable but precision (and oscillations) are bad

Answer

No, the stability range for the complete control system T(s) is too narrow, unattainable in real life

Answer

The automatic control system T(s) is stable and not great but the best that I could find, so I have to take it

Answer

Yes, for the adequate placement and gain, this controller is able to obtain an automatic control system T(s) stable, precise enough and with both acceptable response speed and small enough (or zero) oscillations

Answer

No, the controller C(s) would be absolutely unstable

Answer

Partially, the complete control system T(s) is stable and precise to step, but the system is too slow

Answer

No, the controller C(s) would need to supply outputs physically impossible for this system

Answer

No, the controller C(s) would be too expensive

Answer

No, the resulting control system T(s) would be non-causal
