Compensators are used in place of classical PID controllers for possible achievement of better performance. Unsatisfactory dynamics of some industrial processes represent an engineering problem that hat to be solved. Highly oscillating processes and very slow processes are examples. In this paper a novel feedback PD compensator based is proposed and applied to control second-order like processes having oscillating characteristics (damping ratio ≤ 0.8). The compensator proposed is capable of controlling the steady-state characteristics of the closed-loop control system and its dynamic characteristics. The advantage of the proposed compensator is its simple structure and tuning using an ITAE objective function. It was possible with the proposed compensator to satisfy a system performance with very low overshoot and settling time. The compensator tuning is reduced to simple relation with the process parameters with correlation coefficient as high as 0.9999.
