First Order Integral Sliding Mode Control for Active and Reactive Current of A Multilevel Inverter Based Distributed Generation Unit

A. Elnady




This paper presents an innovative control scheme for Distributed Generation Systems, DGS, using an efficient version of the first order Sliding Mode Control, SMC. The control law of the SMC is modified in order to improve the tracking and reduce the chattering over the conventional SMC. The modification is focused on the definition of the sliding manifold, sliding surface, which contains an integral term of the error not a differential term like the conventional SMC. The proposed control scheme is applied to a multilevel diode clamped inverter based Distributed Generation Unit, DGU. The proposed control scheme is developed to control the active and reactive currents injected or
absorbed by the power grid. Simulation results are provided to prove the viability of the proposed formulation and practicality of the presented sliding mode controller for the distributed generation system.
