| Abstract |
This paper proposes the design of a discrete sliding control of a three-phase active filter based on
feedback linearization techniques. The active filter is controlled through two control loops. The inner
control loop is regulated by a discrete sliding mode control in order to achieve the active wave-shaping
function of the active filter. The outer voltage loop regulates the average voltage on the dc bus
capacitor. The discrete sliding control surfaces are designed by imposing a desired dynamic behavior
on the system, which allows us to determine the main parameters of the sliding mode controller. This
procedure leads to discrete-time switching surfaces, which provides robustness with regard to external
disturbances, and a good dynamic response of the filter. |
