ABSTRAK

Magnetic levitation maglev adalah gaya tolak atau gaya tarik yang yang didapatkan dari medan magnet sehingga menghasilkan celah gap. Gaya tersebut dapat dimanfaatkan pada teknologi kendaraan transportasi massal seperti kereta api cepat. Selain lebih cepat dibandingkan kereta konvensional keuntungan dari sistem maglev antara lain ramah lingkungan bebas friksi dan lubricant. Tujuan penelitian ini adalah untuk mengetahui pengaruh dari jumlah lilitan dan kontrol umpan balik dalam menjaga lebar celah pada maglev. Sistem maglev attractive yang digunakan untuk mendapatkan levitasi yang stabil. Dengan jumlah lilitan dan arus yang diberikan secara bertahap akan menghasilkan besarnya variasi gaya levitasi. Gaya levitasi yang didapatkan kemudian diatur untuk menghasilkan lebar celah gap. Lebar celah kemudian dijaga dengan cara memberi feed back control kontrol umpan balik untuk menjaga tegangan pada sensor. PID kontrol dengan metode Ziegler-Nichols dan manual tuning yang digunakan sebagai kontrol umpan balik untuk menjaga tegangan. Spesifikasi dari sistem maglev yang dibuat adalah baut dengan diameter 5 mm kawat tembaga berdiameter 0.75 mm hall effect sensor HAL 513 modul mikrokontroler Arduino uno massa objek levitasi 12 g dan power supply sebesar 5 dan 12 V. Hasil penelitian menunjukan adanya peningkatan sebesar 0.014 Tesla T tiap penambahan 50 lilitan. Arus yang ditambahkan sebesar 5 A akan meningkatkan gaya sebesar 0.11 N. Lebar celah yang dihasilkan memiliki perbedaan antara pemodelan dan pengujian alat. Hasil yang berbeda dikarenakan ada material magnet yang berbeda dan keterbatasan alat. Pemberian nilai Kp 1.25 dan Kd 0.5 pada sistem maglev cukup untuk menghasilkan levitasi yang stabil sebesar 10 mm pada celah maglev.


ABSTRACT

Magnetic levitation maglev is a repulsive or attractive force that results in a gap were obtained from the magnetic field. The force can be applied in mass transportation vehicle technologies such as high speed train system. Beside faster than conventional trains other advantages of maglev system that environmentally friendly free of friction and lubrication. The purpose of this research is to determine the effect of the number of windings large currents given and feedback control to maintain a wide gap on the maglev. Attractive maglev system is used to obtain a stable levitation. The number of windings and a given current will gradually result in large variations in the levitation force. Levitation force obtained by adjusting the width of the gap. Width of the gap was maintained by giving feedback control to maintain the voltage on the sensor. PID control with Ziegler-Nichols method and manual tuning is used as a feedback control to maintain the voltage. Specifications of the maglev system is made bolt with a diameter of 5 mm 0.75 mm diameter copper wire hall effect sensor HAL 513 Arduino Uno microcontroller modules object levitation mass is 12 grams and the power supply at 5 and 12 V. The results showed an increase of 0.014 Tesla T for each additional 50 turns. Currents were added at 5 A will increase the force 0.11 N. There are wide differences between the modeling gap and experimental results. The results are different because there are different magnetic materials and the limitations of the tools. By giving the value of Kp 1.25 and Kd 0.5 on maglev system is enough to produce a stable levitation.
