Abstract

In this paper, a non-linear control technique and an artificial intelligent controller are presented and applied to a single-phase, grid-connected PV system based on the current source inverter (CSI) topology. These techniques are investigated in order to assure a good performance of CSI in term of total harmonic distortion (THD). The design of the non-linear controller is based on the Sliding mode control (SMC) approach to establish the inverter control laws. An analysis based on Lyapunov stability approach is developed to guarantee the global asymptotic stability of the system. The intelligent controller is based on the fuzzy logic controller (FLC) to generate a reference signal. A conventional regulator PI is used in input and output of the FLC to improve the performance. Both control techniques are used to control the injected current and synchronize it with the network. This paper performs a comparative performance evaluation of both approaches. The analytical expectations of the systems are verified using MATLAB/Simulink software environment.
