Abstract (2. Language):
In this paper, PI control of a synchronous motor has been realized by using a PIC 18F452 microcontroller and it has been worked as ohmic, inductive and capacitive with different excitation currents. Instead of solving integral operation of PI control which has difficulties with conversion to the digital system, summation of all error values of a defined time period are multiplied with the sampling period. Reference values of the PI algorithm are determined with Ziegler-Nicholas method. These parameters are calculated into the microcontroller and changed according to the algorithm. In addition, this work designed to provide visualization for the users. Current, voltage and power factor data of the synchronous motor can be observed easily on the LCD instantly.

Bu gali§mada PIC 18F452 mikro denetleyici kullanilarak senkron motorun PI kontrolu gergekle§tirilmi§ ve degijik uyartim akimlarinda enduktif, kapasitif ve omik gali§tirilmasi saglanmi§tir. Sayisal sistemlere donu§umu kari§ik olan PI kontroldeki integral algoritmasini gergeklejtirmek igin integral alma ijlemi yerine, belirli bir zaman dilimi igerisinde alinan tum hata degerlerinin toplaminin ornekleme periyodu ile garpilmasi kullanilmijtir. Cali§mada PI parametrelerinin referans degerleri Ziegler-Nichols ayarlama yontemi ile tespit edilmijtir. Sistemin galijmasi esnasinda bu parametreler, tasarlanan yazilim ile mikro denetleyici igerisinde hesaplanarak belirlenen algoritma gergevesinde e§ zamanli olarak degijtirilmijtir. Ayrica kullaniciya LCD ekran uzerinden anlik olarak sisteme ait akim, gerilim, frekans ve gug katsayisi buyukluklerin gosterilmesi sureti ile galijmaya gorsel bir boyut kazandirilmijtir.
