Embodiment Construction

[0033] Figures 1-3 illustrate example embodiments of prior art process control loops, and it will be appreciated that an understanding of these process control loops is important to a proper understanding and appreciation of the present disclosure.

[0034] Figure 1 shows a first example implementation of a prior art control loop system (100), shown in a throttling control configuration. The control loop system (100) includes: a working machine (110), which in this embodiment includes a pump (such as a rotodynamic pump); an electric motor (120); a final control element (140) (such as a modulating control valve); a sensor (130), such as a flow rate sensor; and a process controller (164). The train (101) is defined as the three main machines in the control loop system (100), namely the pump (110), the motor (120) and the modulating control valve (140). The control loop system (100) further includes: tubing (160) connecting the pump outlet port (116) to the control valve inlet p...
