Design and FPGA-implementation of PID regulator for DC motor speed control

Abstract

With gradual development in technology various sorts of Control systems has come into picture and it has become an integrated part of the society. It plays a major role in our day-2-day life. A Control system is a device that can be used to control, regulate, command and manage other devices.
This thesis looks at how to build a FPGA BASED PID CONTROLLER for DC MOTOR SPEED CONTROL. The field programmable gate array (FPGA) is a semiconductor device that can be programmed after manufacturing. It doesn’t restrict itself to a particular hardware rather allows the user to program product features and functions, adapt to new standards. FPGAs is used for controlling processes where high loop cycle time is required. FPGAs provide high speed operation which makes it more efficient for controller design rather than other DSP chips.
A proportional-integral-derivative (PID Controller) is generic control loop feedback mechanism widely used in industrial control systems. The controller attempts to minimize the error by adjusting the control inputs. The controller can provide control action designed for specific process requirements. The whole thesis focus on implementation of FPGA based PID controller for DC Motor control.
