© 2018 IEEE. Solar energy has become the go-to solution due to its abundance, yet it is unlike many other conventional sources of energy because of its stochastic nature. To maximize the energy harvest of such intermittent source, robust controllers ought to be used. Researchers have accordingly resorted to modern control techniques, predominantly optimal control methods like model predictive control (MPC). Such modern techniques have proven to track references faster and more accurately; however, they do that at the expense of raising computational costs. The MPC framework is used to eliminate the current sensor in previous work; hence, cut down on the hardware cost of the converter. This paper discusses parity of such observer model, presents results and comparisons on the estimation error for the developed model, and explores areas of improvement for the overall system.
