Morphology

linear-quadratic-Gaussian + controller

The phrase is compositionally built from the adjectives 'linear', 'quadratic', 'Gaussian' plus 'controller', so a learner who knows those words can infer it names a specific kind of controller related to linear systems, quadratic criteria, and Gaussian noise. However, the precise technical implications (e.g., combination of a Kalman filter with an LQR and optimal control under stochastic disturbances) require specialised domain knowledge beyond basic word meanings, so the meaning is only partially predictable.

Etymology

The name linear-quadratic-Gaussian controller tells you how it works: linear means it uses simple straight-line math, quadratic means it counts errors by squaring them so big mistakes matter more, and Gaussian means it treats random changes as a bell-shaped 'noise' pattern. So the name says this controller is made to give the 'best' control when the system is simple and disturbances are random.
