Design and Simulation of Voltage Control System for Simscape Boost Converter Model With Disturbances

In this paper, a voltage control system for an applicable Boost converter system under disturbances is presented. The voltage adjustment performance of the Boost converter is governed by a feedback PID controller system. The realism of the proposed power system is validated through using the Simscape environment, which is adopted to model and simulate the PID based Boost converter system. The presented Simscape system is more applicable in real-time than the Simulink model as the model of the Simscape components and devices is built based on practical considerations like tolerance and parasitic elements. PSO optimization algorithm is utilized to develop the performance of the PID controller through operating the converter system based on best values for PID gain parameters. The simulation design of the proposed power system is implemented in the Matlab tool and its results are presented and discussed to evaluate the performance of the presented feedback PID controller. To validate the robustness of the converter performance the voltage adjustment behavior of the PID controller is assessed based on disturbance of supply voltage, reference voltage and resistive load working conditions. Simulation results revealed the ability of the PID controller to reject the supply voltage disturbances and enable the Boost output to track the demand input trajectories effectively.
