Simple Digital Controls from Approximate Plant Models
Hugh Lachlan Kennedy
Two ways of designing low-order discrete-time (i.e. digital) controls for low-order plant (i.e. process) models are considered in this tutorial. The first polynomial method finds t…
On the design of fixed-gain tracking filters by pole placement: Or an introduction to applied signals-and-systems theory for engineers
Hugh Lachlan Kennedy
The Kalman filter computes the optimal variable-gain using prior knowledge of the initial state and random (process and measurement) noise distributions, which are assumed to be Ga…
Noise will be noise: Or phase optimized recursive filters for interference suppression, signal differentiation and state estimation (extended version)
Hugh L. Kennedy
The increased temporal and spectral resolution of oversampled systems allows many sensor-signal analysis tasks to be performed (e.g. detection, classification and tracking) using a…
Improving the frequency response of Savitzky-Golay filters via colored-noise models
Hugh L Kennedy
Savitzky-Golay (SG) filters are finite impulse response (FIR) realizations of least-squares polynomial regression and they are widely used for filtering (e.g. smoothing, interpolat…
Fixed-Gain Augmented-State Tracking-Filters
Hugh L. Kennedy
A procedure for the design of fixed-gain tracking filters, using an augmented-state observer with signal and interference subspaces, is proposed. The signal subspace incorporates a…
