WebInterpretation of the feedback transfer function To appreciate the eﬀect of feedback in system behavior, we ﬁrst start by comparing the closed–loop transfer function (18) to the plant (open–loop) transfer function (14). We observe the following: 1. The plant’s pole is at ¡2 rad/ sec; whereas the closed–loop pole depends on A feed back control system, such as a PID controller, can be improved by combining the feedback (or closed-loop control) of a PID controller with feed-forward (or open-loop) control. Knowledge about the system (such as the desired acceleration and inertia) can be fed forward and combined with the PID output to improve the overall system performance. The feed-forward value alone can often provide the major portion of the controller output. The PID controller primarily has to comp…
