Abstract

Abstract In this research paper the output voltage, analysis, design, and inductor current regulations ripples in enhancing the model of super lift Luo-Converter working under continuous conduction mode using linear quadratic regulator plus proportional double integral controller is proposed. Here the time variations switching performance super lift Luo- Converter and its dynamic characteristics becomes highly complex. In order to enhance the dynamic characteristics, this converter has offered parameters variation, in output voltage and inductor regulations. This super lift Luo-Converter is analyzed for PV system based on the energy sources. The controller parameters of Linear Quadratic Regulator are designed using the reduced order model of positive output elementary super lift Luo-Converter and its Proportional Double Integral Controller parameters are derived by Ziegler-Nichols tuning method. The performance of the Linear Quadratic Regulator plus Proportional Double Integral Controller is verified at different operating conditions for both developing the MATAB/Simulink model in comparisons with Linear Quadratic Regulator plus proportional integral controller. In the simulation results it shows that output voltage in the designed controller and inductor current regulations are produced under various operating regions.
