Considering the wide use of electronic equipments and utilization of newlinerenewable energy sources DC DC converters have found significant attention in newlinethe recent decades The main purpose of DC DC converter is to supply a regulated DC output voltage to a variable load resistance from an unstable DC input voltage The converters are widely used for the control of motor voltage in electric cars ceiling elevators and mine excavation etc Their specific features are the precise control of acceleration with high efficiency and fast dynamic response due to the switching property of the converter and the problem of regulating the arising output voltage DC DC converter is used to stabilize or control the DC voltage of a battery In addition to other applications DC converters feed electric vehicles and domestic inverters Several control methods are used to control boost converters In this PID controllers are used to optimize the boost converter performance In order to obtain the best coefficients of the controllers ANFIS Hybrid BFA PSO UPSO GA Anti windup and MPSO soft computing methods are applied The design of its loop control is quite complex due to the non linearity of its behavior the commutation of a switch makes its equivalent circuit to change continuously with time In this work the coefficients and poles of the closed loop transfer function for the average model approximated linear model of the boost converter are selected using soft newlinecomputing methods with the purpose of improving the dynamic performance of newlinevoltage regulator newline%%%appendix p147-160, reference p161-173.
