Abstract

Kendali kecepatan motor induksi dibutuhkan untuk mengatasi pengurangan kecepatan akibat slip dan menjaga kecepatan stabil sesuai dengan set point. Untuk performa yang lebih baik saat menghadapi proses seperti perubahan set point atau pertambahan beban saat berjalan stabil dibutuhkan sistem kendali yang lebih baik. Pada penilitian ini dirancang kontroler Adaptif PID yang digunakan untuk memecahkan masalah sistem yang nonlinier pada motor induksi. Dimana parameter kontrol pada kendali adaptif terus berubah seiring dengan berjalannya sistem. Parameter kontrol didapat melalui estimasi menggunakan model Recursive Least Square (RLS) yang merepresentasikan hubungan kecepatan dengan tegangan sinyal kontrol dalam satu sampel dan pengaturan hubungan estimator dan kontroler. Adaptif PID mampu memberikan hasil performansi yang lebih baik pada pengujian kecepatan 200, 600, dan 1000 RPM dengan nilai rise time 4.9206, 3.7017, dan 4.2228 detik dan settling time 29.3403, 12.7315, dan 24.4738 detik lebih rendah dibandingkan dengan PID. Kendali adaptif juga telah diuji dan mampu untuk mengatasi perubahan beban dengan waktu 15.17 detik dan perubahan set point dengan waktu 14.51 detik pada kenaikan set point dan 12.05 pada penurunan set point.

In application of machine drive, speed control is required to get the desired speed. The speed control of the induction motor is needed to overcome the speed reduction due to slip and maintain a stable speed according to the set point. For better performance when facing processes such as set point changes or load gain when running stable, a better control system is needed. Conventional PID controllers are not effective for capricious systems. Adaptive PID can be used to solve system problems that are nonlinear. Where the control parameters on adaptive control are constantly changing as the system progresses. Control parameters are obtained through estimation using Recursive Least Square (RLS) of inputs and outputs in a single sample and setting the relationship of the estimator and controller. Adaptive PID was able to provide better performance results at 200, 600, and 1000 RPM speed tests with rise time values of 4.9206, 3.7017, and 4.2228 seconds and settling times of 29.3403, 12.7315, and 24.4738 seconds lower than pid. Adaptive control has also been tested and is able to cope with load changes with a time of 15.17 seconds and set point changes with a time of 14.51 seconds in set point increments and 12.05 on set point increments.
