“…Since the system is always near the reference trajectory, due to feed forward, it is linearized around the reference and a feedback can be designed using simply linear methods. In order to make effective use of feed forward, smooth reference trajectories are required [18].…”

The grid connected series converter is a custom power device that is mainly used for mitigation of voltage sags. In this paper a novel direct flatness-based control (FBC) in cascade configuration, constituted by an outer voltage and an inner current controller, is presented. It can absorb and inject active and reactive power into the grid. Simulation model includes the practical limitation of voltage source converter output voltage and computational delay. Then, the simulations results for the FBC under balanced voltage dips are presented and compared with traditional proportional integral controller. Finally, the sensitivity analysis of the FBC for grid frequency, phase angle jump and inaccurate knowledge of system parameters are presented.

“…Die Parameter des Laboraufbaus findet man in der Tabelle 1. Diese Parameter sind so optimiert, dass eine geringe Stromwelligkeit bei gleichzeitig minimalen elektrischen Verlusten erzielt wird (mehr Details zur Konverterauslegung finden sich in [6]). Der Konverter besitzt im gesamten Betriebsbereich eine Umwandlungseffizienz von über 90%.…”

Zusammenfassung Dieser Beitrag behandelt den Entwurf von Folgereglern für nichtlineare Eingrößensysteme mittels linearer zeitvarianter dynamischer Ausgangsrückführung, die anhand der Linearisierung der Strecke um die Solltrajektorie bestimmt wird. Der Folgeregler besteht aus einem reduzierten Beobachter zur Rekonstruktion der Stellsignale einer linearen zeitvarianten Zustandsrückführung, welche eine stabile Folgefehlerdynamik sicherstellt. Beim Entwurf wird direkt die Ein-/Ausgangsdifferentialgleichung des Reglers durch Eigenwertvorgabe für lineare zeitinvariante Fehlerdifferentialgleichungen bestimmt, was den Entwurf vereinfacht. Anhand eines Laboraufbaus zur Regelung der Drehzahl eines Gleichstrommotors wird gezeigt, dass sich mit der vorgestellten Entwurfsmethodik ein linearer zeitvarianter Folgeregler niedriger Ordnung sowie vergleichsweise einfacher Struktur berechnen lässt.Summary In this contribution the construction of tracking controllers for nonlinear single-input systems using linear time-varying dynamic output feedback is presented. The design is based on a linearization of the nonlinear system along the reference trajectory. The design process is simplified by the fact that directly the inputoutput description of the controller is derived. The effictiveness of the approach is demonstrated for a laboratory setup of a boost-converter driven dc-motor. In this case a low order dynamic feedback with a simple structure is obtained.

“…However, there are some serious problems exist such as underlying non-linear switching/load behavior. This may cause an unsatisfactory dynamic behavior or exhibit a very noisy shape [1]. Therefore, various combinations of dc-dc power converters with dc motors have been reported in a considerable amount of literature [2][3][4][5][6][7][8].…”

This paper implements a speed/current control of a prototype series DC motor using a buck converter model. It first came up with, a performance analysis for current and speed controllers are provided followed by a simulation in MATLAB. Analyzing the discontinuous conduction mode (DCM) of the buck converter along with the non-linear behavior of the mechanical load put us forward to an efficient strategy for the linearization of speed ramp from stall to nominal speed. The strategy uses a neural network training routine to provide a practical modeling on a variety of converter's non-linear effects. Then, the whole procedure as a pre-design simulation study is practically implemented. The use of an AVR-controlled buck converter paves the way to a straightforward combined speed/current control. Meanwhile, it is shown that the constructed set avoids unnecessary complicated control system while preserving a very fast and desirable response.
