Parameter Estimation of Nonlinearly Parameterized Regressions without Overparameterization nor Persistent Excitation: Application to System Identification and Adaptive Control
Romeo Ortega, Vladislav Gromov, Emmanuel Nuño +2
In this paper we propose a solution to the problem of parameter estimation of nonlinearly parameterized regressions--continuous or discrete time--and apply it for system identifica…
Correction to the paper "A robust IDA-PBC approach for handling uncertainties in underactuated mechanical systems"
Alejandro Donaire, Jose Guadalupe Romero, Romeo Ortega
In this note, it is shown that the results claimed in the paper [1]---as well as the examples presented there---are, unfortunately, incorrect.
Voltage regulation in buck--boost coniverters feeding an unknown constant power load: an adaptive passivity-based control
Carlos A. Soriano--Rangel, Wei He, Fernando Mancilla--David +1
Rapid developments in power distribution systems and renewable energy have widened the applications of dc--dc buck--boost converters in dc voltage regulation. Applications include…
New Results on Parameter Estimation via Dynamic Regressor Extension and Mixing: Continuous and Discrete-time Cases
Romeo Ortega, Stanislav Aranovskiy, Anton A. Pyrkin +2
We present some new results on the dynamic regressor extension and mixing parameter estimators for linear regression models recently proposed in the literature. This technique has…
A globally exponentially stable position observer for interior permanent magnet synchronous motors
Romeo Ortega, Bowen Yi, Slobodan Vukosavic +2
The design of a position observer for the interior permanent magnet synchronous motor is a challenging problem that, in spite of many research efforts, remained open for a long tim…
Orbital stabilization of nonlinear systems via Mexican sombrero energy shaping and pumping-and-damping injection
Bowen Yi, Romeo Ortega, Dongjun Wu +1
In this paper we show that a slight modification to the widely popular interconnection and damping assignment passivity-based control method---originally proposed for stabilization…
A New Signal Injection-based Method for Estimation of Position in Interior Permanent Magnet Synchronous Motors
Bowen Yi, Slobodan N. Vukosavic, Romeo Ortega +2
Several heuristic procedures to estimate the rotor position of permanent magnet synchronous motors (PMSM) via signal injection have been reported in the literature. Using averaging…
