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.
