Digital PID Control System for DC Servo Motor Using VHDL Code

This project investigates based PID motion control systems for small, self- adaptive systems. The closed loop position control of DC servo motor is performed using PWM signal. VHDL based PID motion control system provides an efficient and cheap method. Proportion (P) increases gain margin, increase system response speed Integration (I) -minimizes steady state error Differentiation (D) increases system stability. VHDLHARDWARE DESCRIPTION LANGUAGES (HDLS) are used to describe hardware for the purpose of simulation, modeling, testing design and documentation of digital systems. PWM PULSE WIDTH MODULATION Which circuit works by making a square wave. Advantage of pulse width modulation is that the pulses reach the full supply voltage and will produce more torque in a motor
