The process value (PV), and setvalue (SV) or setpoint are on the same scale for easy comparison. The controller output CO is shown as MV (Manipulated variable) range 0-100% A control loop using a discrete controller. Field signals are process variable (PV) from the sensor, and control output to the valve (the Final Control Equipment - FCE).
An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.
A programmable logic controller (PLC, for smaller, less complex processes) or a distributed control system (DCS, for large-scale or geographically dispersed processes) analyzes this sensor data transmitted to it, compares it to predefined setpoints using a set of instructions or a mathematical model called the control algorithm and then, in ...
Process capability is the ability of a process to produce output within specified limits. [1] To help determine whether a manufacturing or business process is in a state of statistical control, process engineers use control charts, which help to predict the future performance of the process based on the current process.

CEO pay includes salary, bonuses, stock sales, and other payments. Average CEO Pay is calculated using the last year a director sat on the board of each company. Stock returns do not include dividends. All directors refers to people who sat on the board of at least one Fortune 100 company between 2008 and 2012.
A proportional–integral–derivative controller (PID controller or three-term controller) is a feedback-based control loop mechanism commonly used to manage machines and processes that require continuous control and automatic adjustment.
