Sliding mode direct power control strategy of a power quality based on a sliding mode observer

• The design of a SM controller using SMO which aims to simplify the control procedure.
• According to the justified tendency of reduction of the number of the sensors.
• The sliding mode observer has been presented as a robust estimation method.

The first problem in our third millennium is energy. For this raison, we try to find a new solution to develop different ways of distribution and energy use. This article presents the design of a sliding mode controller using sliding mode observation technique which aims to simplify the control procedure. According to the justified tendency of reduction of the number of the sensors. The sliding mode observer has been presented as a robust estimation method. We propose a new multi-function converter as an efficient solution to improve the power quality. For improving the quality of the energy transfer from the power supply to the load, and reducing the harmful effects of the harmonics generated by nonlinear load. The good dynamic and static performance under the proposed control strategy is verified by simulation and experiment.
