In this paper, a new approach to the variable structure system design with conventional PI term and additional low-pass filter is considered. This method can be used for increasing the system steady-state accuracy. In this approach, the sliding mode occurs only in the controlled plant and the sliding manifold order is not increased, unlike similar variable structure control algorithms. The efficiency of such a control approach is verified by digital simulation results of illustrative control systems: unstable plant control and DC motor speed control.
Übersicht
In diesem Aufsatz wird ein neuer Ansatz für den Entwurf eines Systems von variabler Struktur mit konventionellem PI-Term und zusätzlichem Tiefpaßfilter betrachtet. Dieses Verfahren kann zur Erhöhung der stationären Systemstabilität verwendet werden. Hierbei tritt die Sliding-Mode nur in der geregelten Strecke auf, und die Ordnung der Mengen wird im Gegensatz zu ähnlichen Regel algorithmen für variable Strukturen nicht erhöht. Die Wirksamkeit einer solchen Regelung wird durch digitale Simulationsergebnisse beispielhafter Regelsysteme verifiziert, nämlich instabile Strecken regelung und Drehzahlregelung eines Gleichstrommotors.
