Thus when |T(s)| =1 and T θ (s) = -180 degrees, the system is unstable. The open-loop gain and phase determines the stability of a system. It may seem confusing to call T(s) the open-loop gain when it ...

In temperature regulation, there are two types of systems: open loop and closed loop. Deciding which methodology to choose depends on the requirements of the process. Open-loop heating. Open-loop ...
