Noise Covariance Estimation for Time-Varying and Nonlinear Systems

Kalman-based state estimators assume a priori knowledge of the covariance matrices of the process and observation noise. However, in most practical situations, noise statistics are often unknown and need to be estimated from measurement data. This paper presents a new auto-covariance least squares method for noise covariance estimation of linear time-varying and nonlinear systems. The new algor...

Finite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay

In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...

kT/C noise: Covariance matrix calculation of instationary noise in time-varying systems

The voltage variance at a capacitance C with a noisy resistance in parallel is kT/C, even if the resistance is infinite. This so-called kT/C noise may dominate in switched-capacitor circuits. In this paper kT/C noise is treated analytically, using explicit and implicit notations of differential equations. The resulting algorithms can be implemented in any circuit simulator with transient analys...

ADAPTIVE FUZZY TRACKING CONTROL FOR A CLASS OF NONLINEAR SYSTEMS WITH UNKNOWN DISTRIBUTED TIME-VARYING DELAYS AND UNKNOWN CONTROL DIRECTIONS

In this paper, an adaptive fuzzy control scheme is proposed for a class of perturbed strict-feedback nonlinear systems with unknown discrete and distributed time-varying delays, and the proposed design method does not require a priori knowledge of the signs of the control gains.Based on the backstepping technique, the adaptive fuzzy controller is constructed. The main contributions of the paper...

A New Method for Detecting the Time-Varying Nonlinear Damping in Nonlinear Oscillation Systems: Nonparametric Identification

This paper presents an original method that can be used for identifying time-varying nonlinear damping characteristics of a nonlinear oscillation system. The method developed involves the nonparametric identification, in which only the system responses, namely, displacement and velocity need to be known for the identification. However, themethod is concernedwith a Volterratype integral equation...
