Bulanık Anahtarlama Algoritması ile DTC Kontrollü Asenkron Makine için İyileştirilmiş Tork ve Hız Performansları

Direct Torque Control (DTC) is a vector control method based on the of stator flux in desired direction. The achieved by direct selection optimum inverter output voltage vectors. limit values trajectory determined rotation are using hysteresis controllers. In this study, performance analysis two different methods for reducing speed and torque oscillations three-phase asynchronous motor controlled presented. Matlab/Simulink simulation studies, analyses were made references motor, both transient steady state changes presented comparatively. When obtained results examined, it seen that new fuzzy-based controller, which offered instead Proportional Integral Derivative (PID) controller used traditional control, significantly decreases specific conditions oscillations. However, considering structure simple plain has been preserved. According to obtained, shown Fuzzy Logic (FL) gives better result than PID at t=4.5 seconds.
