Design of Stabilizing Controllers for Interval Systems

The controllers of standard PI and PID type play the essential role in contemporary industrial practice. Therefore, the simple techniques of controller tuning are still demanded, especially in case that these algorithms are able to cope with various uncertain conditions. The contribution is focused on control design for interval systems using the computation of all possible stabilizing PI controllers in combination with the choice of the final one through an algebraic approach. The needful amount of theory is followed by an example.
