Abstract
Programmable Logic Controller (PLC) merupakan sebuah perangkat untuk mengontrol sebuah plant. Plant yang digunakan dalam hal ini adalah motor DC. Motor DC biasanya menjadi penggerak mesin produksi dan mesin CNC, Biasanya penggunaan sensor untuk mengetahui kecepatan dari motor DC. Salah satu metode pengestimasian adalah observer. Tujuan dari tugas akhir ini merupakan pengimplementasian observer kecepatan untuk mengestimasi kecepatan dari motor DC untuk menjadi sensorless. Software yang digunakan untuk simulasi merupakan Totally Integrated Automation (TIA) Portal adalah Software dari Siemens yang memiliki banyak program didalamnya digunakan untuk memprogram HMI, PLC, drive. Dalam hal ini Observer yang digunakan adalah Leunberger Observer reduced order observer. Persamaan reduced order observer akan dimasukkan kepada blok perhitungan PLC. Untuk implentasi Observer pada PLC dibutuhkan output voltase dari plc sendiri 0-10 V dan pembuatan function block untuk observer. Input yang digunakan merupakan analog input. Hasil pengimplementasian observer memiliki ess dengan rata-rata 1,833%. Observer dapat diimplementasikan terhadap PLC dengan persamaan observer yang diinput terhadap function block di PLC.
