In this paper, Reduced-Order Observer For Real-Time Implementation Speed Sensorless Control of Induction Using RT-LAB Softwareis presented. Speed estimation is performed through a reduced-order observer. The stability of the proposed observer is proved based on Lyapunov’s theorem. The model is initially built offline using Matlab/Simulink and implemented in real-time environment using RT-LAB package and an OP5600 digital simulator. RT-LAB configuration has two main subsystems master and console subsystems. These two subsystems were coordinated to achieve the real-time simulation. In order to verify the feasibility and effectiveness of proposed method, experimental results are presented over a wide speed range, including zero speed.

In this paper, using synthesis of a hybrid control is applied to the speed of an induction motor feed by three-level inverter. Based on the combination of the fuzzy logic and the sliding mode approach, this method has the advantage of combining the performances of the two types of controllers. The fuzzy logic confers a very appreciable flexibility to the reasoning which uses and makes it possible to take into account Imprecisions and uncertainties, The sliding mode is a controller for nonlinear systems with non-constant parameters; it leads to precision and robustness, and allows solving problems obtained by conventional control laws. To lift the stresses of external disturbance and makes the system more performing and more robust, the two controllers of fuzzy logic and sliding mode are combined.

“…Teknik pengontrolan motor induksi dapat dilakukan dengan metode kontrol sakelar. Kontrol skalar dilakukan dengan linierisasi model persamaan non linier motor induksi saat beroperasi pada keadaan mantap (steady state), yaitu dengan menjaga perbandingan antara besarnya tegangan stator (magnitude) terhadap frekuensi (ω) agar selalu bernilai konstan [2] sehingga nilai fluks dan torsi maksimum selalu konstan.…”

Teknik pengontrolan motor induksi tiga fasa yang digunakan pada penelitian ini adalah kontrol tegangan dan frekuensi (Volt/Hertz). Metode kontrol tersebut, mampu menjaga besarnya fluks dan nilai torsi maksimum agar tetap konstan. Metode Modulasi Ruang Vektor (Space Vector Modulation) ditanamkan pada mikrokontroler STM32F100 untuk pembangkitan pulsa PWM inverter sesuai dengan urutan pensakelaran inverter tiga fasa sumber tegangan (VSI). Lebar pulsa dari tiap pulsa PWM ditentukan oleh pengaturan variabel waktu dalam SVM. Kontrol sistem dilakukan secara loop terbuka dengan mengubahubah nilai set point kecepatan yaitu mengatur nilai frekuensi yang secara bersamaan mengatur nilai tegangan sesuai nilai indeks modulasi. Penggunaan kontrol skalar (Volt/Hertz) mampu menahan lonjakan arus mula motor saat motor mulai dijalankan secara langsung, yaitu besarnya arus mula motor sebesar 3,12 A dapat ditekan menjadi � 2,9 A. Nilai rata-rata error pengukuran pada pengujian kecepatan motor sesuai dengan nilai faktor slip yaitu sebesar 6%. Nilai kecepatan motor yang dihasilkan memiliki hubungan linier dengan nilai frekuensi yang diberikan. Semakin kecil nilai tegangan keluaran inverter, maka semakin besar nilai THD dan semakin besar harmonisa yang dihasilkan oleh motor yang menyebabkan motor tidak dapat bekerja secara optimal. Implementasi dari sistem kontrol memberikan rata-rata nilai error 1,935%.Kata Kunci: motor induksi, Volt/Hertz, STM32F100, inverter, SVM
