Digital P-I-D Controller Implementation for Speed Control Applications Using FPGA

C. Pratibha Rohini | A. M. Prasad

Abstract: This paper deals with the implementation of PID controller for a DC fan controller application on FPGA platform (both hardware and software). The PID controller is implemented on Spartan 3E FPGA by using Xilinx software version 9.2. The PWM signal is generated by FPGA Spartan 3E board, which further given to DC fan for its speed control. The PID controller is prototyped and verified on the Xilinx Spartan 3E Field Programmable Gate Array (FPGA) platform and a test bench is written for top module (PID controller) which is simulated by using ModelSim simulator. The verification of DC fan operation is checked using generated PWM signal generator.
