Adaptive control of linear time varying systems
(1996)A new class of adaptive controllers for linear time varying systems is designed and analyzed using nonlinear design techniques and the certainty-equivalence approach. It is established that this new class of controllers ...

Algebraic approaches for fault identification in discrete-event systems
(2005)In this note, we develop algebraic approaches for fault identification in discrete-event systems that are described by Petri nets. We consider faults in both Petri net transitions and places, and assume that system events ...

Backstepping Control of Linear Time-Varying Systems with Known and Unknown Parameters
(2003)The backstepping control design procedure has been used to develop stabilizing controllers for time invariant plants that are linear or belong to some class of nonlinear systems. The use of such a procedure to design ...

Distributed stochastic power control for time-varying long-term and short-term fading wireless networks
(2007)In this paper, new time-varying wireless channel models that capture both the space and time variations of longterm and short-term fading wireless networks are developed. The proposed models are based on stochastic ...

Estimation and identification of time-varying long-term fading channels via the particle filter and the em algorithm
(2011)In this paper, we are concerned with the estimation and identification of time-varying wireless longterm fading channels. The dynamics of the fading channels are captured using a mean-reverting linear stochastic differential ...

Inference for Some Multivariate ARCH and GARCH Models
(2003)Multivariate time-varying volatility models have attracted a lot of attention in modern finance theory. We provide an empirical study of some multivariate ARCH and GARCH models that already exist in the literature and have ...

Nonlinear control design for linear time varying systems
(1996)A new class of linear controllers for linear time varying systems are proposed. These controllers are based on nonlinear tools such as integrator backstepping and nonlinear damping, and on a new filter structure that ...

Stable indirect adaptive control of continuous-time systems with no a priori knowledge on the parameters
(Publ by Pergamon Press Inc, 1993)A crucial drawback of indirect adaptive control is the stabilizability or controllability of the estimated plant model which is required in order to calculate the controller parameters. Loss of stabilizability at a particular ...
