Abstract

In recent years Evolutionary Computation has come of age, with Genetic Algorithms (GA) being possibly the most popular technique. A study is presented revealing the performance of a GA in determining the PID tuning parameters for a multivariable process, including decoupling controllers. The process used for this investigation is a distillation column which is a MIMO high-order, nonlinear system. The results indicate some limitations of using GAs for controller tuning when MIMO systems are involved.
