State estimation and estimator based predictive control of nonlinear autonomous hybrid systems poses a challenging problem as these systems involve discontinuities that are introduced by switching of the discrete variables. In this paper, we propose a state estimation scheme for an autonomous hybrid system using an ensemble Kalman filter (EnKF), which belongs to the class of particle filters an...

This article discusses the identification of nonlinear dynamic systems using multi-layer perceptrons (MLP). It focuses on both the structure uncertainty and parameter uncertainty which have been widely explored in the 10 literature of nonlinear system identification. The main contribution is that an integrated analytic framework is proposed for automated neural network structure selection, para...

It is shown that switching among stable linear systems results in a stable system provided that switching is “slow-on-the-average.” In particular, it is proved that exponential stability is achieved when the number of switches in any finite interval grows linearly with the length of the interval, and the growth rate is sufficiently small. Moreover, the exponential stability is uniform over all ...

In this paper we develop a globally stabilizing stability-based switching controller for a three-state lumped parameter centrifugal compressor surge model. The proposed model involves pressure and mass flow compression system dynamics as well as spool dynamics to account for the influence of speed transients on the compression surge dynamics. The proposed nonlinear switching controller architec...

An integrated design of switching laws and feedback controllers for uncertain switched nonlinear control-affine systems with an arbitrary number of subsystems is developed. Sufficient conditions for the existence of globally asymptotically stabilizing state feedback laws are derived using the control Lyapunov function approach. Additionally, an explicit rule for constructing switching laws and ...

This paper considers an optimal control problem for switched nonlinear systems. The objective is to minimize an associated cost functional, by finding an appropriate continuous control input and location switching strategy. We propose an extension of an algorithm based on strong variations to handle constraints on both locations and switching instants. Numerical experiments testify the viabilit...

The paper by Liana, Zhao, and Dimirovskid shows one of the latest advances in switched systems by incorporating sliding mode control with a nonlinear integral switching surface. It is worthwhile comparing two types of switching mechanisms employed in this work. The first type is the system structural switching with an average dwell time. Hence, the switching frequency should be finite, and the ...

In this paper we deal with switching fuzzy filtering design problems for a class of discrete-time nonlinear stochastic systems with time-varying distributed delays. To investigate the system stability, the considered nonlinear stochastic systems is presented by switching fuzzy stochastic models. To relax the stability conditions, an improved free-weighting matrix technique and the piecewise Lya...

This paper investigates the almost sure H∞ sliding mode control (SMC) problem for nonlinear stochastic systems with Markovian switching and time-delays. An integral sliding surface is first constructed for the addressed system. Then, by employing the stopping time method combined with martingale inequalities, sufficient conditions are established to ensure the almost surely exponential stabilit...
