The effects of proportional-integral-derivative (PID) controller position within the structure of control system loop on system time domain performance parameters were investigated. PID controller was connected as series compensation, feedback compensation and series-feedback compensation respectively. The connected PID controller’s gains were tuned. The transfer function for the uncompensated, series compensated, feedback compensated and series-feedback compensated systems were developed, and then subjected to a step input forcing function, which yielded time-domain performance parameters for these systems. The obtained time domain parameters show that the series compensated system has the most superior performance quality compared with other compensated and uncompensated systems.
