Abstract

The paper presents a method for design of robust PI controllers for systems with interval uncertainty. The method is based on plotting the stability boundary locus in the (kp,ki)-plane and sixteen plant theorem. The stability boundaries obtained for interval plants split the (kp,ki)-plane in stable and unstable regions. The parameters of robust PI controllers are chosen from the stable region. The designed robust PI controller is used for control of a laboratory chemical continuous stirred tank reactor (CSTR). The reactor is used for preparing of NaCl solution with desired concentration. The conductivity of the solution is the controlled variable and the volumetric flow rate of water is the control variable.
