Recent progress in the use of singular perturbation and two-time-scale methods of modeling
and design for control systems is reviewed. Over 350 references are organized into major …

Many realistic engineering systems are large in dimension and stiff for computation. Their
analysis and control require extensive numerical algorithms. The methodology of singular …

A graph-theoretic method of extreme simplicity is proposed for decomposition and clustering
of complex systems into interconnected subsystems with prescribed interaction strength. The …

Output feedback control of linear time-invariant singularly perturbed systems is studied. The
set of all compensators that stabilize a singularly perturbed system while preserving its two …

This paper addresses the problem of fault tolerant estimation and the design of fault tolerant
sensor networks. Fault tolerance is defined with respect to a given estimation objective …

The H/sub 2/guaranteed cost control problem for a singularly perturbed norm-bounded
uncertain system is addressed using the quadratic stabilizability framework. After defining …

We consider the problem of “stabilizing” uncertain, singularly perturbed, linear, time-varying,
systems whose fast dynamics can be unstable. We propose a class of nonlinear composite …

We treat the problem of robustness of output feedback controllers with respect to singular
perturbations. Given a singularly perturbed control system whose boundary layer system is …

Sequential LQG algorithms are formulated for stochastic linear discrete-time systems having
a lower block triangular (LBT) decomposition. Three distinct information structures are …

This paper presents a structural view of fault-tolerant estimation algorithms. Structural
analysis makes it possible to identify the minimal submodels by which unknown variables …
