摘要：A maximum power point tracking (MPPT) technique based on linear quadratic regulator (LQR) approach for solar photo-voltaic system has been proposed in this paper. LQR based MPPT controller has been designed with online set-point adjustment approach using current, radiation and temperature sensors. Real time simulations have been carried out on MATLAB TM /dSPACE TM platform for solar photo-voltaic system with buck converter. Performance of the proposed technique hase been compared with perturb and observe, incremental conductance, fuzzy logic, neural network and ANFIS based methods of maximum power point tracking. Experimental results showed the superiority of the proposed method for tracking maximum power point under rapidly varying solar radiations.
