Abstract EN
In this paper, a MIMO PI design procedure is proposed for linear time invariant (LTI) systems with multiple time delays.
The controller tuning is established in two stages and guarantees performances for set-point changes, disturbance variations, and parametric uncertainties.
In the first stage, an iterative linear matrix inequality (ILMI) approach is extended to design PI controllers for systems with multiple time delays without performance guarantee, a priori.
The second stage is devoted to improve the closed-loop performances by minimizing sensitivity functions.
Simulations results carried out on the unstable distillation column, the stable industrial scale polymerization (ISP) reactor, and the non-minimum phase 4-tank benchmark prove the efficiency of the proposed approach.
A comparative analysis with the conventional internal model control (IMC) approach, a multiloop IMC-PI approach, and a previous ILMI PID approach proves the superiority of the proposed approach compared to the related ones.
