Abstract
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
controller (ANC) combines the nonlinear feedback
linearization technique with linear adaptive control
techniques and takes into account the uncertainties in the model parameters .We Apply an adaptive nonlinear control in order to control the line-currents, output DC link voltages and also to reduce the influence of the parameter uncertainty. Simulation results clearly show that the proposed controller has a good performance and robust to
the parameter uncertainties compared with other nonlinear strategies controllers.
