Abstract :
A necessary condition for the existence of a stable PID controller for a given plant is introduced. The derived rule is straightforward to check and applies generally for LTI systems, including time-continuous, time-discrete and time-delay systems. Therefore, the plot of a directly constructing function is checked for a required minimal number of real zeros.
