Abstract: Proportional Integral Derivative (PID) controller is the most recommended controller in industries that does not require precise analytical model of the system to be controlled. This paper presents a Design, Analysis and Modeling of PID (Proportional -Integral-Derivative) controller based on FPGA (Field-Programmable Gate Arrays) for Synchronous Multiphase DC-DC Converters in Automotive Applications. Mat lab Simulink is used for the PID controller design to generate a set of coefficients associated with the desired controller characteristics. This simulation platform also integrates tools for a future implementation of the PID controller embedded in a FPGA controller. The main contribution of this work is to implementation of a PID controller that can be used independently of the number of phases of the converter, making it suitable to be applied in a wide range of high power applications. This controller has been designed having in mind, the goal of developing a real-time FPGA-based controller, so the complexity has been reduced to a minimum. Hybrid vehicles, aerospace, naval industry, process control, manufacturing, robotics and automation and transpiration system power systems can also benefit from the development of this controller.
