Kontrol Kecepatan Putaran Permanent Magnet Synchronous Machine (PMSM) Menggunakan PID, FLC Dan ANFIS

Permanent Magnet Syschronous Machine (PMSM) has low torque in a number of specific applications, so a good control model is needed. PMSM uses the principle of faraday experiments by turning a magnet in a coil by utilizing another energy source ... When a magnet moves in a coil or vice versa. Turning the engine will change the magnetic force flux in the coil and penetrate perpendicular to the coil so that there is a potential difference between the ends of the coil. That is due to changes in magnetic flux. To get the best control method, a comparison of several speed control models is needed. In this study comparing PMSM speed control without controller, using PID controller, using FLC controller, and using ANFIS controller. From the simulation results show that the best model on ANFIS controller, which is closest to the Speed reff (300 rpm) is ANFIS obtained the round profile with the smallest undershot of 300,015 rpm at t = 0.0055 seconds and steady state at 300.02 rpm at 0.004 seconds, obtained output current profile best on FLC = 3.39 A, while at ANFIS = 3.38 A, the best torque profile (the smallest overshot) is obtained on the ANFIS controller of 0.28 pu, the best voltage profile (most continuous) on the ANFIS controller is 300.03. The results of this study will be continued with the use of other artificial intelligence.

Rancang Bangun Sistem Deteksi Kebakaran Gedung di Universitas Islam Lamongan Berbasis Mikrokontroller Menggunakan Radio Frekuensi

The process of firing is always unpredictable and predicted in advance. When it comes, what causes it, the level of coverage and how much impact it causes, are things that cannot be predicted by human capabilities. The design of a fire safety system that aims to improve the safety and comfort of occupants in the building. The analysis carried out is to measure and record temperature and conduct a series of several experiments. Temperature is equipped with Celsius (C) units and smoke uses PPM units (parts per million). By working, the smoke sensor and temperature will detect itself and work properly. And this is to avoid any errors caused by rising temperatures due to sunlight or smoke from cigarettes. If the LM35 temperature sensor reaches 40 C then the temperature will detect and the buzzer will sound the LED will be wrong and the LCD 2x16 will display "CAUTION THERE'S ASAP". If Smoke reaches from 600 upwards the smoke sensor will detect and the buzzer will sound, the LED light will light up then on LCD 2x16 will display "CAUTION THERE IS FIRE"

Analisis Koordinasi Sistem Proteksi Trafo Distribusi 20 KV (Studi Kasus PT. PLN PERSERO Unit Lamongan)

Electric power distribution systems that use air cables or ground cables often experience various disturbances. Interference that often occurs is symmetry or non-symmetric interference which can be a short relationship between one phase to the ground, between phases or the breakdown of one or more. To find out the magnitude of the interference current, an analysis of the transformer distribution system is needed to determine the disturbances that will occur.The transformer which is the main equipment in a GI must be considered in order to get the proper current circuit and security. Designing the right transformer setting is an effort to protect equipment, systems and consumer needs from disturbances that may occur in the distribution system. The calculation of the fault current and the magnitude of the nominal current of the transformer will be used as an important reference in determining the transformer settings in the distribution of voltage to consumers.From the results of these calculations it can be concluded that the performance time of feeder relays is slower than the time of relay in the event. The data in the field is still in the right condition (the difference is not too far), so that the overall OCR-GFR setting in the field is still in good condition.

Distribution system is divided into primary and secondary distribution networks. The primary distribution network is the network of the substation to the distribution, while the secondary distribution is the channel network from the substation transformer is distributed to the consumer or the load. Primary distribution network is better known as medium voltage network (JTM 20kV) while secondary distribution is low voltage network (JTR 220 / 380V).
