Abstract :
Controlling the solar panels to extract maximum solar energy is an important concern of control engineers these days. An approximate second order model of a sun seeker control system is controlled using lead, lag, and lead-lag controller. The response of these controllers is compared with the proposed robust controller. Subsequently it is observed that the robust controller outperforms in providing reliability and stability in case of parameter variations under practical circumstances. The results are simulated in MATLAB.
