Lyapunov function-based control of active power filters to reduce the adverse effects of harmonics on induction motors

In this study, a pulse width modulator controller inverter type active power filter is used for reducing the adverse effects of harmonics. Induction motor control system used in this study comprises a proportional-integral controller, a direct torque control algorithm, and an inverter module. Nonlinear controller algorithm proposed in this study enables setting different parameters in the controller system. Our experimental results show that more planar electromagnetic torque can be obtained by using the proposed controller-based filter than a classical controlled-based filter.
