Mathematical models of control system used in power supply circuits

Abstract

Using mathematical models in electronic systems is widespread when we talk about simulation. If PSpice use this type of models in simulation of electronic circuits, we can use also in simulation of control systems. Current trend in electronic systems is to improve the complexity of the systems, due mainly complex tasks and good accuracy. A general system has multiple inputs and multiple outputs and time varying. From this, we can obtain a simplify model for a simple system. In this paper, we present a study for generating of a mathematical model for an electronic system which appear in control system of a power supply circuit. That model will be implemented in Simulink and after that, the result will be compared with PSpice. This type of study is used in learning process for students to help them to understand the functionality of this type of circuits.
