Prashant Kumar , Ravi Mishra. "Implementation of FPGA based PID Controller for DC Motor Speed Control System". International Journal of Engineering Trends and Technology (IJETT). V4(3):471-476 Mar 2013. ISSN:2231-5381. published by seventh sense research group.


In this paper, the implementation of software module using 'VHDL' for Xilinx FPGA (XC2S30) based PID controller for DC motor speed control system is presented. The tools used for building and testing the software modules are Xilinx ISE 9.1i and ModelSim XE III 6.3c. Before verifying the design on FPGA the co mplete design is simulated using Modelsim Simulation tool. A test bench is written where, the set speed can be changed for the motor. It is observed that the motor speed gradually changes to the set speed and locks to the set speed.
