The most monly used technique is pulsewidth modulated DC speed (PWM) DC converter technology, which has speed, high precision, fast response, wide speed range and low and the wear and tear. This paper presents a PWM generated by the AVR microcontroller ATmega16 signal, RI2110driven, the determinant of the keyboard control and LCD display, and to take speed, the current dualloop PID algorithm to DC motor speed control of DC motor PWM speed control system.
