In this study, the authors have applied a jump parameter linear optimal control technique for the Cuk converter used in photovoltaic systems. The simulation results for the Cuk converter used for maximum power point tracking are presented. The results show how the feedback gains impact the optimal performance of the two states of the Cuk converter, and indicate complete freedom in choosing the values of the duty cycle (from the optimal performance point of view). In addition, the optimal controller for the jump linear system with integral action is applied to the Cuk converter and the simulation result is compared with that for the Cuk converter averaged system. The superiority of the proposed technique can be clearly seen from the simulation results obtained. The presented technique can be used for other applications of the Cuk converter and not necessary only for the solar cells.
