Pengaturan Kecepatan Motor DC Dengan Mikrokontroler dengan BASCOM AVR

Suparno, M.Pd16:56Bascom AVR Tidak ada komentar

Penggunaan motor DC dewasa ini sudah sangatlah umum, salah satu kelebihan motor DC adalah relatif gampang didapat dan mudah diatur kecepatan putarnya. Secara umum pengaturan kecepatan motor DC adalah dengan menggunakan cara analog. Pada artikel kali ini akan dibahas contoh cara mengatur kecepatan motor DC dengan menggunakan mikrokontroller.

Mikrokontroler yang digunakan adalah Tipe AVR dari Atmel seperti mikrokontroler Atmega 8535, 16, 32. Informasi kecepatan motor akan ditampilkan pada modul LCD HD4480. Sedangkan sebagai driver motor menggunakan modul driver motor IC L298.

Cara pengaturan kecepatan yang digunakan adalah dengan menggunakan teknik PWM (Pulse Width Modulation), salah satu teknik untuk mengatur kecepatan motor DC yang umum digunakan. Dengan menggunakan PWM kita dapat mengatur kecepatan yang diinginkan dengan mudah. Teknik PWM untuk pengaturan kecepatan motor adalah, pengaturan kecepatan motor dengan cara merubah-rubah besarnya duty cycle pulsa. Pulsa yang yang berubah ubah duty cycle-nya inilah yang menentukan kecepatan motor. Besarnya amplitudo dan frekuensi pulsa adalah tetap, sedangkan besarnya duty cycle berubah-ubah sesuai dengan kecepatan yang diinginkan, semakin besar duty cylce maka semakin cepat pula kecepatan motor, dan sebaliknya semakin kecil duty cycle maka semakin pelan pula kecepatan motor. Sebagai contoh bentuk pulsa yang dikirimkan adalah seperti pada gambar 1, pulsa kotak dengan duty cycle pulsa 50%. Sedangkan sebagai contoh bentuk pulsa PWM adalah seperti pada gambar 2.

Seperti pada gambar 1, semakin besar duty cycle pulsa kotak, maka semakin lama pula posisi logika high. Jika motor diatur agar berjalan ketika diberi logika high, maka jika memberi pulsa seperti pada gambar 1 diatas, maka motor akan berada pada kondisi “nyala-mati-nyala-mati” sesuai dengan bentuk pulsa tersesebut. Semakin lama motor berada pada kondisi “nyala” maka semakin cepat pula kecepatan motor tersebut. Motor akan berputar dengan kecepatan maksimum jika mendapat pulsa dengan duty cycle 100%. Dengan kata lain motor mendapat logika high terus menerus.

Dengan mengatur besarnya duty cycle pulsa kotak yang dikirimkan, kita dapat mengatur banyaknya logika high yang diberikan pada motor, dengan kata lain mengatur lamanya waktu motor untuk berputar dalam satu periode pulsa. Jika lamanya waktu motor untuk berputar dalam satu periode pulsa ini berubah maka kecepatan purtaran motor juga akan berubah, sesuai dengan duty cycle atau waktu motor untuk berputar dalam satu periode pulsa.
