Path following of a class of underactuated mechanical systems via immersion and invariance-based orbital stabilization
Bowen Yi, Romeo Ortega, Ian R. Manchester +1
This paper aims to provide a new problem formulation of path following for mechanical systems without time parameterization nor guidance laws, namely, we express the control object…

On Generation of Virtual Outputs via Signal Injection: Application to Observer Design for Electromechanical Systems
Bowen Yi, Romeo Ortega, Houria Siguerdidjane +2
Probing signal injection is a well-established technique to extract additional information from a weakly (or non) observable dynamical system. Using averaging theory, a framework t…

An Adaptive Observer for Sensorless Control of the Levitated Ball Using Signal Injection
Bowen Yi, Romeo Ortega, Houria Siguerdidjane +1
In this paper we address the problem of sensorless control of the 1-DOF magnetic levitation system. Assuming that only the current and the voltage are measurable, we design an adap…
