The non-interactive form of controller is the classical teaching model of PID algorithms. It gives a student a clear understanding of P, I and D control, since: P-control, I-control and D-control can be seen independently of each other. Then, PID is effectively a combination of independent P, I and D-control actions. This can be seen in Figure 7.1.
