When there is a disturbance in the power grid, some power generator units are
disconnected from the grid. The frequency starts to decrease. Therefore, multi-stage …

The passivity-based control (PBC) is a new direction of nonlinear control, but the method is
basically a qualitative method. A quantifiable design method in combination with PBC is …

Using active and passive filters is necessary to prevent harmonic distortion of HVDC lines.
This paper, using PHEVs in the case of (v2g) instead of the active filters capacitors by …

this paper presents a proposal of the magnetic levitation (Maglev) ball system by using an
optimal PID position controller. The optimal PID controller is achieved to keep a steel ball …

In this work, the principle of Immersion and Invariance (I&I) is used in the design of an
observer/estimator for a closed-loop magnetic levitation system in order to reconstruct the …
