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…
A New Least Squares Parameter Estimator for Nonlinear Regression Equations with Relaxed Excitation Conditions and Forgetting Factor
Romeo Ortega, Jose Guadalupe Romero, Stanislav Aranovskiy
In this note a new high performance least squares parameter estimator is proposed. The main features of the estimator are: (i) global exponential convergence is guaranteed for all…
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…
