Introduction

Control of rotary speed (RPM) on DC motorcycles is a crucial aspect in various applications, both in the industry and in the automation sector. In an effort to regulate the rotating speed of DC motorcycles, the PID (Proportional-Integral-Derivative) method is often used. This article discusses the design of the DC motorcycle rotating speed control system using the PID method based on the ATmega328 microcontroller.

PID Method in Controlling DC Motorcycles

The PID method consists of three control components: proportional (P), integral (I), and derivatives (D). Each component has a different role in maintaining the stability of the motor rotating speed.

Proportional (P)

This section serves to respond directly to the error (error) between the desired speed and the actual speed. The greater the error, the greater the output produced. The proportional component is responsible for making adjustments to the motor speed based on the current error. This component is essential in maintaining the stability of the motor speed.

Integral (I)

This component serves to correct systematic errors that may not be resolved by P control by accumulating errors from time to time, control I can help achieve the target value more precisely. The integral component is responsible for making adjustments to the motor speed based on the accumulated error over time. This component is essential in achieving the target value.

Derivative (D)

This section estimates changes in speed, so that it can anticipate future mistakes and give faster responses. The derivative component is responsible for making adjustments to the motor speed based on the rate of change of the error. This component is essential in anticipating future mistakes and giving faster responses.

System Implementation

Microcontroller ATmega328 plays an important role in this system. He not only counts DC motorbike rpm but also sends the RPM value to the CVAVR program and PWM signal (Pulse Width Modulation) to the motor driver. By using PWM, we can control the average voltage received by the motor so that it can adjust the speed more accurately.

DC motor speed regulation can be done through two methods:

Using a finished DC motor driver: This method involves using a pre-made DC motor driver that can regulate the speed of the motor.
or by using a transistor circuit set to provide PWM signals: This method involves using a transistor circuit to provide PWM signals to the motor driver.
