Modelling and Control of a Chopper using Feedback and Feedforward Control Schemes
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 5
Abstract
Designing two degree of freedom controller to control the boost chopper system is challenging. A new feedforward combined with feedback controller design is proposed. Increasing the efficiency of the DC-DC converters can be achieved by decreasing the distortion and noise for both input and output stages in the system. A linearization mathematical model analysis for boost chopper is presented. Both the input voltage with multiple steps and the duty cycle of PWM which control the switching circuit were applied to study the behaviour of the system. In this study, the simulation results show that the disturbance rejection and input tracking were improved for different cases and situations. Also, the results show that the proposed method can be adapted by redesigning the feedforward controller to recover the impact of the boost parameter changes.
