Özet
In this paper a study is presented about the
reduction of electromagnetic interference (EMI) in Direct
Torque Control (DTC) method by the means of chaotic space
vector modulation. Space Vector Modulated Direct Torque
Control (SV-DTC) is a method developed to reduce current
and moment fluctuations which stem from the hysteresis
controllers used in classical DTC method. The switching
frequency amplitude was changed chaotically in a Space
Vector Modulated Direct Torque Control (FFSV-DTC) having
a Fixed switching frequency, and Chaotic Space Vector
Modulated Direct Torque Control (CAFSV-DTC) method
having chaotic amplitude modulated switching frequency was obtained. CAFSV-DTC method was suggested to reduce EMI,
acoustic noise and current harmonics which occur in FFSV- DTC method. For this purpose, the proposed CAFSV-DTC
method, using a Permanent Magnet Synchronous Motor
(PMSM) drive, is compared to Random Amplitude Frequency
method (RSV-DTC) and FFSV-DTC. Simulation results
indicate that the proposed method yields better results.
