Novel PD-I Controller for Underdamped Second Order-Like Processes

This research paper aims at investigating the use of a novel PD-I controller to control second order underdamped processes. Controller tuning based on using MATLAB control and optimization toolboxes. Using the suggested tuning technique, it is possible to eliminate completely the kick characteristic associated with PID controllers and some other tuning techniques. The tuning results of the proposed PD-I controller are tabulated for process damping ratio from 0.1 to 0.6 and from 0.7 to 0.95 while the natural frequency of the second order process covers a range from 5 to 15 rad/s
