Smooth, Time-invariant Regulation of Nonholonomic Systems via Energy Pumping-and-Damping
Bowen Yi, Romeo Ortega, Weidong Zhang
In this paper we propose an energy pumping-and-damping technique to regulate nonholonomic systems described by kinematic models. The controller design follows the widely popular in…
Orbital Stabilization of Nonlinear Systems via the Immersion and Invariance Technique
Romeo Ortega, Bowen Yi, Jose Guadalupe Romero +1
Immersion and Invariance is a technique for the design of stabilizing and adaptive controllers and state observers for nonlinear systems. In all these applications the problem cons…
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…
