Abstract

Motor listrik merupakan motor yang merubah energi listrik menjadi energi mekanik, salah satu contoh motor listrik adalah motor induksi 3 fasa. Motor ini bekerja dengan menggunakan induksi elektromagnet yang ada di dalam lilitan stator ke lilitan rotornya. Lalu motor ini membuat sebuah gaya elektromotif (emf) atau biasa disebut sebagai tegangan induksi. Motor induksi biasa digunakan di bidang industri karena terkenal dengan kuat dan kendali yang baik. Untuk mengatur kecepatan motor ini digunakan inverter sejenis Variable Frequency Drives. VFD merupakan perangkat elektronik yang digunakan untuk memvariasikan frekuensi tegangan AC untuk mengatur kecepatan motor AC. VFD yang digunakan pada penelitian ini adalah Altivar V610. Selain VFD digunakan kontroler PI yang dapat mengendalikan wahtru steadystate serta sistem tanpa overshoot. Untuk mengatur angka PI digunakan algoritma genetik sebagai optimisasi kontroler. Didapatkan bahwa menggunakan algoritma genetic dengan operasi genetic yang besar pada kontroler PI dapat meredam overshoot pada sistem dengan memberikan output steadystate sesuai dengan setpoint pada sistem. Dengan menggunakan PI – GA menghasilkan sistem dengan angka kecepatan RMSE rata – rata ±65 RPM. Selain implementasi, digunakan simulasi pada Matlab untuk mengatur angka PI – GA ini.

An electric motor is a motor that converts electrical energy into mechanical energy, one example of an electric motor is a 3-phase induction motor. This motor works by using electromagnetic induction in the stator winding to the rotor winding. Then this motor creates an electromotive force (emf) or commonly referred to as an induced voltage. Induction motors are commonly used in industry because they are known for their strength and good control. To regulate the speed of this motor, an inverter such as Variable Frequency Drives is used. VFD is an electronic device that is used to vary the frequency of the AC voltage to regulate the speed of the AC motor. The VFD used in this study is Altivar V610. In addition to the VFD, a PI controller is used which can control the steady state current and make a system without overshoot. To set the PI number, a genetic algorithm is used as controller optimization. It was found that using a genetic algorithm with large genetic operations on the PI controller can reduce overshoot in the system and also providing a steady state output according to the set point in the system. Using PI - GA results in a system with an average RMSE speed figure of ±65 RPM. In addition to the implementation, simulations are used in Matlab to set these PI – GA numbers.
