Nonlinear Control of Single-Phase Shunt Active Power filter Theoretical analysis of closed-loop performances
The problem of controlling single-phase shunt active power filter is addressed in presence of nonlinear loads. The control objective is twofold: (i) compensation of harmonic and reactive currents absorbed by the nonlinear load; (ii) regulation of the inverter output capacitor voltage. A two-loop cascade control strategy is developed that includes an inner-loop designed, using the backstepping t...
متن کاملSingle-Phase Shunt Active Power Filter Using Indirect Control Method
A single-phase shunt active power filter is used mainly for the elimination of harmonics in single-phase AC networks. In this paper a single-phase shunt active power filter based on, an indirect control technique is designed and simulated. This control technique is achieved by phase shifting the input signal(voltage/current) by π/2.The overall action of the shunt active power filter to eliminat...
متن کاملAdaptive Nonlinear Control of Three-Phase Shunt Active Power Filters
The problem of controlling three-phase shunt active power filters (SAPF) is addressed in presence of nonlinear loads supplied with three-phase power grids. The SAPF-load system is shown to be modeled, in the ( , ) coordinate frame, by a third-order nonlinear state-space representation. The control objective is twofold: (i) compensating for the current harmonics and the reactive power absorbed b...
متن کاملMitigation of Switching Harmonics in Shunt Active Power Filter Based on Variable Structure Control Approach
This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...
متن کاملAdaptive Nonlinear Control of Three Phase Shunt Active Power Filter with Uncertainties
This paper presents a new control strategy for a three phase shunt active power filter, which consists of applying an adaptive nonlinear control. This technique consists of applying an adaptive nonlinear control to the uncertain nonlinear model of shunt active power filter obtained in (dq) frame by using the power balance between the input and output sides. The designed Adaptive nonlinear contr...
