manipulated variable

Controlled and manipulated variables now having concrete significance for students.

Measured variables can be brought in, as well as manipulated variables.

In real systems, there are practical limits to the range of the manipulated variable (MV).

The experimenter then observes whether variation in the manipulated variables cause differences in the dependent variable.

Manipulation checks are measured variables that show what the manipulated variables concurrently affect besides the dependent variable of interest.

In the real world, this is D to A converted and passed into the process under control as the manipulated variable (or MV).

The plant P has two inputs, the exogenous input w, that includes reference signal and disturbances, and the manipulated variables u.

It is called either the manipulated variable (MV) or the control variable (CV).

Finally, it was necessary to identify an optimal choice of manipulated variables and product specification, such that a high reproducibility of product performance was achieved.

These signals are then transmitted automatically to the final control elements which act to alter the manipulated variable in such a manner as to reduce the error signal.

Exel will chart the data correctly if the manipulated variable is in a left hand column and the responding variable in the column to the right.

Control system design can be separated into three steps: selection of the controlled and manipulated variables, selection of control algorithm and parameter tuning.

The PID control scheme is named after its three correcting terms, whose sum constitutes the manipulated variable (MV).

Firstly, it was not clear if the combination of manipulated variables and product specification definition that were selected was adequate to ensure the end process reproducibility sought.

This is verified by random assignment, manipulation before measurement of the dependent variable, and statistical tests of effect of the manipulated variable on the dependent variable.

Batch Trajectory Optimization The quality of a product at the end of a batch is dependent on the initial feed conditions and the trajectories of all manipulated variables over the course of the batch.

SLC (single loop controller) - Single loop controllers are appliances that monitor an input variable and effect change on a control output (manipulated variable) to hold the input variable to a setpoint.

It actively constructs that view though a series of "selected and manipulated variables," such as the time of day, the position of the camera and whether it moves, the type of lens, and the editing (Gibson 215).

A major threat to the validity of causal inferences is confounding: Changes in the dependent variable may rather be attributed to the existence or variations in the degree of a third variable which is related to the manipulated variable.

Any deviations, such as changes in grade, drag, wind speed or even using a different grade of fuel (for example an ethanol blend) are corrected by the controller making a compensating adjustment to the fuel valve open position, which is the manipulated variable.
