| dc.description.abstract | Power converters are electronic devices designed to transform and regulate electrical energy for wide range of uses, from small-scale devices like tablets that run on milli-Watts to large-scale power systems to control Mega-watts. There are three main types of DC-DC converters: boost (output voltage higher than input voltage), buck (output voltage lower than input voltage), and buck-boost (either step-up or step-down) converters. In this thesis, two control techniques-proportional-integral-derivative (PID) and sliding mode control (SMC) are used to model and regulate a DC-DC boost converter. We developed a mathematical model of the boost converter using fundamental circuit concepts, resulting in a bilinear system representation. Classical linear control techniques, such as proportional integral- derivative (PID) control, have been extensively employed for boost converter control. However, linear controllers may exhibit limitations when dealing with the nonlinearities, parameter variations, and uncertainties inherent in boost converter systems. To solve these problems, in this study, a sliding mode control (SMC) was designed based on its nonlinear dynamic modeling. This technique has the potential to address the nonlinear nature of the system, provide an improved transient response, and maintain stability across a wide range of operating conditions. The stability analysis of the boost converter was performed using Lyapunov’s stability criterion. The performance of the SMC and PID controllers under various disturbances is thoroughly compared in this work. Across a range of disturbances, the SMC outperformed the PID. measured by figuring out the disturbance Integral Time Absolute Error (ITAE) improvement as a percentage. In particular, it attains an improvement of 97.87% under nominal conditions and 94.86% under modest controller variation. Furthermore, as compared to PID, the SMC showed better robustness in the face of disruptions. By creating Matlab Real-Time Environment (RTE) simulation results using MATLAB software, the efficacy of the suggested control method was confirmed. | |
