Abstract
Tugas akhir ini membahas desain kontroler fuzzy-PID pada plant motor induksi tiga fasa. Motor induksi tiga fasa merupakan jenis motor yang sering digunakan pada dunia industri. Hal ini dikarenakan kelebihan dari motor induksi tiga fasa yaitu konstruksinya sederhana, harganya murah dan murah dalam pemeliharaan. Namun pengaturan kecepatan motor induksi jauh lebih sulit dibandingkan motor DC. Untuk mengatur kecepatan motor induksi pada kecepatan tetap diperlukan pengaturan terhadap frekuensi atau torsi, padahal tidak ada hubungan yang linear antara arus motor dengan torsi yang dihasilkan.
Permasalahan pada tugas akhir ini adalah sulitnya menjaga kecepatan putar motor induksi tiga fasa agar tetap konstan pada saat terjadi perubahan beban. Untuk mengatasi permasalahan tersebut, diperlukan sebuah desain kontroler. Metode kontrol yang digunakan adalah fuzzy-PID. Metode kombinasi ini dipilih karena kontroler PID hanya dapat mengatasi plant satu fungsi alih saja, sehingga kontroler fuzzy diperlukan untuk metode penalaan terhadap parameter PID.
Implementasi kontroler fuzzy-PID dilakukan oleh DAQ Advantech tipe USB 4716 dengan bantuan software LabView. Hasil implementasi menunjukkan bahwa respon dapat mempertahankan kecepatan mendekati nilai set point dengan error 0,67% - 1,7%. Dan spesifikasi respon beban minimal dan maksimal telah mendekati respon beban nominal, dengan rata-rata ts(5%) sebesar 0,67 detik, tr(10% - 90%) sebesar 0,45 detik, dan td sebesar 0,16 detik.

This final project explores the fuzzy-PID controller design in three-phase induction motor plant. Three phase induction motor is a type of motor that is often used in the industrial world. This is because the advantages of the three-phase induction motor is simple construction, low cost and low in maintenance. However, the induction motor speed control is much more difficult than DC motors. To adjust the speed of the induction motor at a constant speed required for frequency setting or torque, but there is no linear relationship between current motor with torque generated.
Problems in this final project is the difficulty of keeping the rotational speed three-phase induction motor to remain constant in the event of load changes. To overcome these problems, we need a controller design. Control method used is the fuzzy-PID. A combination of methods have been selected PID controller can only be overcome plant transfer function only, so the fuzzy controller is required for tuning method for PID parameters.
Implementation of Fuzzy-PID controller made by Advantech DAQ USB type 4716 with the help of software Labview. The implementation results show that the response can maintain speeds approaching the set point value with an error of 0.67% - 1.7%. And the specification of minimum and maximum load response has approached the nominal load response, with an average of ts(5%) by 0.67 seconds, tr (10% - 90%) by 0.45 seconds and 0.16 seconds td.
