These can include, for example, the addition of feedback loops from output to input, in doing so creating models analogous to closed-loop control theory. Putting I-P-O To Use ...

The open-loop control system is a continuous control system that provides no feedback from its output. The control process, therefore, is only affected by the system’s input. Traditionally, electrical ...

2 Benefits and 1 Drawback of Key Process Input Variable. Understanding how to influence and control product or process variation with KPIVs is fundamental to the adoption of Six Sigma principles.

As the technology developed in the 1970s and 1980s, more complex approaches and strategies developed, involving multiple inputs and outputs with more complex models. Eventually, multivariable, ...

Mechanical control systems (staplers, car windows) use parts for movement/force control. They include input, process, and output. Types of motion: linear, rotary, reciprocating, oscillating.

This versatile high-side current limiter uses negative-feedback control based on general process-control principles (Fig. 1). Figure 2 illustrates a practical implementation.
