A robust PID tuning method based on the parameter space approach is presented. In two steps a robust PID controller setting is designed which simultaneously satisfies pole location and gain/phase margin criteria. The plant model may be an arbitrary LTI time delay system with uncertain parameters (including the time delay), which are restricted by an operation domain.
