In this paper design and implementation of low power Proportional Integral Derivative (PID) controller using Field Programmable Gate Array (FPGA) is presented. In the present status the embedded control applications requires low power and fast acting PID controllers with a closed loop performance using less resources, resulting in cost reduction. Different types of digital PID controllers are analyzed with the frequency response using Matlab tool. The controller algorithm is synthesized, simulated and implemented using Xilinx Spartan3e XC3S100E board with XilinxISE 9.1i as a tool and synthesized and simulated using Altera Cyclone EP1C12Q240C8 with Quartus II 6.1 as a tool. The results are compared in terms of their power consumption, speed, memory usage, Look Up Tables (LUTs) and number of Multipliers, Adders/Subtractors.
