Small disturbances can trigger cascading failures in power grids
Yubo Huang, Junguo Lu, Weidong Zhang
With the sharp increase of power demand, large-scale blackouts in power grids occur frequently around the world. Cascading failures are the main causes of network outages. Therefor…
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…
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…
On State Observers for Nonlinear Systems: A New Design and a Unifying Framework
Bowen Yi, Romeo Ortega, Weidong Zhang
In this paper we propose a new observer design technique for nonlinear systems. It combines the well-known Kazantzis-Kravaris-Luenberger observer and the recently introduced parame…
