Mahalanabis, A., Lobbia, R. N., Willman, C. R.
Within the discipline of Combat ID, as related to high performance fighters, a problem of significant proportion that arises is how to determine quickly and accurately a target's ID. Various...
On optimum receivers for analog communication in impulsive noise (1978)
Madan, B, Prasad, S, Mahalanabis, A
In this paper the problem of impulsive noise suppression in analog communication systems is considered. The problem of demodulation of amplitude and phase modulated signals in the presence of...
Two-stage identification of closed-loop systems (1977)
Prasad, R, Sinha, A, Mahalanabis, A
A two-stage identification method based on modeling error compensation for systems operating in closed loop is presented. The feedback regulator is assumed linear, time-invariant. The model structure...
Continuous time smoothing for systems with interrupted observations (1976)
General continuous time smoothing results for state estimation with interrupted observations are derived. The interruption mechanism is characterized by a jump Markov process taking values 0 or 1....
Finite lag receivers for analog communication (1975)
The problem of designing optimum receivers with a finite built-in delay, for a class of stochastic signals, is considered. The approach used here is based on the so-called fixed-lag smoothing...
On optimal stationary control of systems with state dependent noise (1975)
This note proposes a simplified existence criterion for the linear quadratic optimal control law for systems with state dependent noise.
On the stability of a fixed lag smoother (1973)
The aim of this correspondence is to show that the fixed lag smoothing algorithm reported earlier by the authors is asymptotically stable and is computationally better than the other stable smoothers...
On the computational aspects of two recent smoothing algorithms (1973)
This note is concerned with a consideration of the computational requirements of fixed-lag and fixed-point smoothing algorithms reported recently by the authors.
Frequency-domain criteria for stability of a class of nonlinear stochastic systems (1973)
Mahalanabis, A, Purkayastha, S
The problem of finding frequency-domain conditions that are sufficient to ensure asymptotic stability with probability one (ASWP 1) of a Lure-type system with white-noise input disturbance is...
Optimal smoothing for continuous-time systems with multiple time delays (1972)
Equations for the smoothed state estimate and for the error covariances of a continuous-time system with multiple time delays, based on observations involving time delays, are derived through a...
Optimal fixed lag smoothing for time delayed system with colored noise (1972)
The aim of this note is to report an algorithm for the fixed lag smoothing problem of a time delayed system whose observations contain colored noise. This is derived by looking at the appropriate...
On minimizing the divergence in discrete filters (1972)
The problem of divergence that often arises when the filter mechanization is based on lower order process dynamics is examined. This situation may be caused, for example, by the impossibility of...
On the Lyapunov design of systems with zeros in the right-half plane (1970)
The effect of a zero in the right-half plane on the controller derived through the stability theorem of Lyapunov is considered through a simple illustrative example. It is shown that the controller...
