    The authors consider the standard H∞-control problem for more general nonlinear systems modeled by equations in which the penalty output and the measured output are, in general, functions of the state, the exogenous input, and the control input. In particular, we characterize a family of H∞ controllers via output feedback as well as state feedback, solving the pro... View full abstract»

  • Stability analysis of systems with impulse effects

    The authors establish conditions for the uniform stability and the uniform asymptotic stability of equilibria of systems with impulse effects described by systems of nonlinear, time-varying ordinary differential equations. Under mild additional assumptions, these sufficient conditions turn out to be necessary as well. For the case of time-invariant systems with impulse effects described by nonline...

  • Useful nonlinearities and global stabilization of bifurcations in a model of jet engine surge and stall

    Compressor stall and surge are complex nonlinear instabilities that reduce the performance and can cause failure of aircraft engines. We design a feedback controller that globally stabilizes a broad range of possible equilibria in a nonlinear compressor model. With a novel backstepping design we retain the system's useful nonlinearities which would be cancelled in a feedback linearizing design. Th... View full abstract»

  • Nonlinear overtaking optimal control: sufficiency, stability, and approximation

    The authors consider infinite-horizon nonlinear optimal control problems with unbounded performance indexes using notions of overtaking optimality. In the framework of optimal control, new sufficient conditions of Caratheodory-Hamilton-Jacobi type for both weak overtaking and overtaking optimality are presented and compared with known results from the calculus of variations setting. Using local st... View full abstract»

    We study the convergence of two stochastic approximation algorithms with randomized directions: the simultaneous perturbation stochastic approximation algorithm and the random direction Kiefer-Wolfowitz algorithm. We establish deterministic necessary and sufficient conditions on the random directions and noise sequences for both algorithms, and these conditions demonstrate the effect of the &ldquo...

  • Reliable decentralized stabilization of linear systems

    Reliable stabilization of linear time-invariant multi-input/multi-output plants is considered using a two-channel decentralized controller configuration. Necessary and sufficient conditions are obtained for existence of reliable controllers that maintain stability under the possible failure of either one of the two controllers. All decentralized controllers that achieve reliable stabilization are ... View full abstract»

  • A large deviations perspective on the efficiency of multilevel splitting

    We analyze the performance of a multilevel splitting method for rare event simulation related to one recently proposed in the telecommunications literature. This method splits promising paths into subpaths at intermediate levels to increase the number of observations of a rare event. In our previous paper (1997) we gave sufficient conditions, in specific classes of models, for this method to be as... View full abstract»

  • Uncoupled Riccati iterations for the linear quadratic control problem of discrete-time Markov jump linear systems

    Publication Year: 1998, Page(s):1727 - 1733
    Cited by:  Papers (16)

    This paper deals with recursive methods for solving coupled Riccati equations arising in the linear quadratic control for Markovian jump linear systems. Two algorithms, based on solving uncoupled Riccati equations at each iteration, are presented. The standard method for this problem relies on finite stage approximations with receding horizon, whereas the methods presented here are based on sequen... View full abstract»

  • Consistency of open-loop experimental frequency-response data with coprime factor plant models

    The model/data consistency problem for coprime factorization considered is: Given some possibly noisy frequency-response data obtained by running open-loop experiments on a system, show that these data are consistent with a given family of perturbed coprime factor models and a time-domain L∞ noise model. In the noise-free open-loop case, the model/data consistency problem boils do... View full abstract»

  • Rejection of persistent ℒ-bounded disturbances for nonlinear systems

    A nonlinear L1-control problem, which deals with the rejection of persistent bounded disturbances for nonlinear systems, is investigated. The concept of invariance plays an important role in the L1-performance analysis and synthesis. The main idea is to construct an invariant subset in the state space such that achieving disturbance rejection is equivalent to restricting the ... View full abstract»
