Difference Grey Predictor Compensated Moving Sliding Mode Controller of a Digital Signal Processing-Based Solar Powered Communication Systems

Abstract—In this paper, a difference grey predictor (DGP) compensated moving sliding mode controller (MSMC) for solar powered communication systems. The proposed methodology combines the merits of DGP and MSMC. The MSMC can shorten the reaching phase and ensure the sliding mode occurrence from an arbitrary initial state. However, as the loading is a severe nonlinear condition, the MSMC will undergo chatter and steady-state error problems, thus deteriorating the performance of solar powered communication systems. The DGP is thus used to remove the chatter while the system uncertainty bounds are overestimated and to reduce the steady-state error while the system uncertainty bounds are underestimated. With the proposed methodology, the robustness of the communication system can be enhanced expectably, and a high-quality solar power sinusoidal output with low voltage harmonics and fast dynamic response can be obtained even under nonlinear loading. The theoretic analysis, design process, and digital signal processing (DSP)-based experimental implementation for solar powered communication systems are presented to verify the efficacy of the proposed methodology.

Index Terms—Difference grey predictor (DGP), moving sliding mode controller (MSMC), solar powered communication systems, voltage harmonics, digital signal processing (DSP).
