Adaptive observer for a nonlinear system with partially unknown state matrix and delayed measurements
Olga Kozachek, Alexey Bobtsov, Nikolay Nikolaev
Problem of an adaptive state observer design for nonlinear system with unknown time-varying parameters and under condition of delayed measurements is considered. State observation…
Parameter Estimation of Two Classes of Nonlinear Systems with Non-separable Nonlinear Parameterizations
Romeo Ortega, Alexey Bobtsov, Ramon Costa-Castello +1
In this paper we address the challenging problem of designing globally convergent estimators for the parameters of nonlinear systems containing a non-separable exponential nonlinea…
Adaptive observer for a LTV system with partially unknown state matrix and delayed measurements
Alexey Bobtsov, Nikolay Nikolaev, Olga Slita +1
Problem of adaptive state observer synthesis for linear time-varying (LTV) system with unknown time-varying parameter and delayed output measurements is considered. State observati…
Adaptive state observer for linear time-varying system with partially unknown parameters of the state matrix and the input vector
Alexey Bobtsov, Nikolay Nikolaev, Romeo Ortega +2
The article deals with the problem of synthesis of an adaptive observer of state variables of a linear time-varying SISO dynamic system. It is assumed that the control signal and t…
An Almost Globally Stable Adaptive Phase-Locked Loop for Synchronization of a Grid-Connected Voltage Source Converter
Daniele Zonetti, Alexey Bobtsov, Romeo Ortega +2
In this paper we are interested in the problem of adaptive synchronization of a voltage source converter with a possibly weak grid with unknown angle and frequency, but knowledge o…
