A linear system in which the mean squared error between the desired output and the actual output is minimized when the input is a random signal generated by white noise.

INTEGRAL SQUARE ERROR

A measure of system performance formed by integrating the square of the system error over a fixed interval of time; this performance measure and its generalizations are frequently used in linear optimal control and estimation theory.

INTEGRAL-MODE CONTROLLER

A controller which produces a control signal proportional to the integral of the error signal.

HODGSON NUMBER

Method of predicting the metering error during pulsating gas flow when a surge tank is located between the pulsation source (pump or compressor) and the meter (orifice, nozzle, or venturi).

GYRO ERROR

The error in the reading of the gyrocompass, expressed in degrees east or west to indicate the direction in which the axis of the compass is offset from true north.

HALVING

The process of adjusting magnetic compass correctors so as to remove half of the deviation on the opposite cardinal or adjacent intercardinal headings to those on which adjustment was originally made when all deviation was removed. This is done to equalize the error on opposite headings.

HYSTERESIS ERROR

That error in the reading of an instrument due to hysteresis
