Abstract Self-tuning algorithms based on modified minimum variance criteria have been implemented and tested in a commercial microcomputer based process automation system. The algorithms have been realized on two levels, physically in separate microcomputer units. This have been done in a natural way by separating the control and parameter estimation tasks. Because communication between the microcomputers takes place periodically after certain time interval, which usually is greater than the basic control interval, the parameters are not renewed after each control interval as usually done. The minimum variance criteria has been applied to tune also standard PI-type algorithms. The paper discusses on experiences and details in realization.
