Abstract
Motor induksi merupakan jenis motor yang paling banyak
digunakan di industri dibandingkan dengan motor listrik yang lain,
karena jenis motor ini memiliki beberapa keuntungan diantaranya
konstruksinya yang sederhana, kokoh, harga relatif murah dan tidak
memerlukan pemeliharaan yang rumit. Namun permasalahan utama dari
bahasan ini adalah menjaga agar kecepatan putar motor tetap konstan.
Jika motor induksi diberi beban yang berubah sampai pada nilai tertentu
dari beban nominalnya, maka responnya akan mengalami perubahan
walaupun kontroler telah diberikan. Sehingga pengaturan kecepatan
motor induksi tiga fasa jauh lebih sulit dilakukan. Untuk mengatasi
permasalahan tersebut digunakan teknik kontrol optimal yaitu metode
Linear Quadratic Regulator (LQR) Gain Scheduling. Kontroler ini
dipilih karena dapat otomatis beradaptasi dengan cara mengubah
parameternya untuk menyesuaikan diri terhadap perubahan parameter
plant. Hasil pengujian kontroler LQR Gain Scheduling mampu
mempertahankan kecepatan motor pada tiap kondisi pembebanan. Hasil
respon mendekati respon beban nominal dengan spesifikasi sebesar
0,34 detik, ts (5%) sebesar 1,02 detik, tr (5%-95%) sebesar 1 detik, td
sebesar 0,28 detik, dan ess sebesar 0,6%.

Induction motor is a type of motor most widely used in the industry
compared to other electric motors, because this type of motor has
several advantages such as simple construction, sturdy, relatively cheap
price and does not require complicated maintenance. But the main
problem of this discussion is to keep the motor speed remains constant.
If the induction motor load changes given to the particular value of the
nominal load, then the response will change even if the controller has
been given. Thus the speed control of three phase induction motor is
much more difficult. For overcome these problems, optimal control
techniques used namely Linear Quadratic Regulator (LQR) Gain
Scheduling. The controllers have been selected because it can
automatically adapt by changing its parameters for adjust from plant
parameters changes. Results test LQR Gain Scheduling controller can
maintain the speed of motor in every condition encumbering. Results
response approaching response nominal load to the specifications of
at 0,34 second, ts (5%) at 1,02 second, tr (5%-95%) at 1 second, td at
0,28 second, and ess at 0,6%.
