Disturbance and Noise
Disturbance and noise affect the system, typically in an undesirable way. Disturbances are generally external to the system, whereas noise most often is internal. They are both of similar nature and can be dealt with using many of the same integrated modeling tools, although disturbances sometimes can be deterministic, whereas noise generally is stochastic. We shall here focus on disturbances and noise of stochastic nature. Examples are wind loads, atmospheric wavefront aberrations, and noise in transducers of various types.
