Abstract: This paper concentrates on the work done on controller using Field Programmable Gate Array (FPGA) technology. FPGA based realization offers high speed, complex functionality, consume less power, and provides parallel Processing. Proportional-Integral-Derivative (PID) controllers are universal control structure and have widely used in Automation systems. A PID is widely used in feedback control of industrial processes on the market in 1939 and has remained the most widely used controller in process control until today. The work is done on PID Controller and working status of PID Controller is shown through its one of application i.e. a line follower Car which is used in industry for parcels and stuffs transports. For such an PID to obtained an pre-defined output a Car is created which may called as a application of PID Controller. The car is composed by three cards DE0-Nano main card, SCD(Smart Car Daughter card) daughter card, and sensor daughter card. The SDC daughter card includes the lamp, buzzer, motor driver DRV8833, IR receiver, ADC chip LT2308, and TMD (Terasic Mini Digital) expansion header. The sensor daughter card includes seven Photo Interrupters used to track dark line (s) on a white background. Proportional-integral-derivative (PID) controller is a vastly used control algorithm for many real-time control applications and among many types of PID controller, FPGA based PID controller is one of the effective one. FPGA can offer parallel processing, more speed and easy to implement. In this paper, we focused our works designing PID controller with its application by Field Programmable Gate Arrays (FPGAs) with some parameter change so that the cost will be minimized and accuracy will be maximized.
