Performance Optimization of the Regulation Loop of a Buck Chopper Driven by Duty Cycle Modulation
Duty Cycle Modulation (DCM), Linear Quatratic Regulator (LQR), Buck Chopper Driven, Pulse Width Modulation (PWM).
The control of switching power supplies in general, and particularly type Buck is a topic much discussed and highly invested by sense current technological applications simultaneously require a high level of accuracy and performance, and DC-DC converters have a very important role to play in systems requiring conversion and adaptation of the energy level. We were interested in the course of this work to the optimal control of a Buck controlled by the duty cycle modulation diet, with the aim of optimizing the performance of the control loop of our Buck chopper DCM. An analysis of modeling approaches and control law synthesis to ensure stability and to guarantee a certain level of performance throughout the area have been studied in this work while takingin to account the problems of their application inan industrial environment. Our study based on the optimal control of the Buck chopper controlled by the DCM allowed us both in the design of the continuous state model and in the design of the discrete state model and through the LQR controller (Linear Quatratic Régulator) to discuss the responses of our system in closed loop and open loop. By exploring advanced control laws, we were able to control our system, namely the state variable that we want to control and to impose a very small overshoot, and consequently a very damped dynamic regime. We believe that we have been able to provide power electronics systems with systematic methods to model, analyze and control DC-DC converters using optimal control and the DCM technics.
