The aggressiveness of a PI controller is defined and a quantitative characterization is given in relation to the ratio of the proportional and integral actions of the controller. This concept provides simple analytic design relations for tuning PI controllers. It is illustrated by simulation results obtained with a test batch of processes representative of(More)
New explicit design relations for setting the controller parameters in PI control of industrial processes are proposed. The objective is to obtain proper transient responses with smooth control actions minimizing the variations of the controller output, hence preserving actuators from untimely attrition. The use of the proposed relations is illustrated by(More)
