Abstract
The problem of controlling an unstable delayed double integrating process using a feedback first-order lag-lead compensator is studied. The effect of time delay of the process in a range between 0.1 and 0.8 seconds is considered. The compensator is tuned using MATLAB optimization toolbox with five forms of the objective function in terms of the error between the step time response of the closed-loop control system and the response steady-state value. Using the proposed compensator with the delayed double integrating process indicates the robustness of the compensator in the time delay range used with superior time-based specifications. The dynamics of the control system are compared with other technique based on using a feedforward first-order lag-lead compensator.
