Noise Cancellation Systems
Suppose that you have a signal Y (Y can be a time series, a parametric surface or a volumetric data series) corrupted by a Gaussian noise with unknown variance. It is often of interest to know more about this variance. EVAR(Y) thus returns an estimated variance of the additive noise.EVAR provides...

Unknown Input Observers(UIO) are used in model based FDI schemes to reduce or almost eliminate the effect of unknown disturbances on the plant/system.Further they can be used to generate residuls that are insensitive to unknown disturbances or noise, thus lower the false alarm rate.For isolation...
