Abstract
The problem of a rule base development containing PI-controller setter’s experience is considered. As a result, it is decided to divide such base into several blocks, which are responsible for P-component and I-component parameters adjustment for cooling and heating processes respectively. The conditions when rules should be activated were determined. They depend on the plant parameters at the moment. Proposed rule base is a part of PIcontroller parameters tuner. It was tested on models of two real heating furnaces with different parameters. According to the conducted experiments, a conclusion could be made that overshoot caused by plant nonlinearity is lower for the control system with a proposed tuner in comparison with the system with a conventional PI-controller. That leads to saving of about 24 % of time needed to follow a setpoint schedule. So PI-controller parameters tuner usage based on developed rule base allows to take into consideration plant nonlinearity, to intensify production and to reduce production costs.
