Study of direct torque fuzzy control technology based on FPGA

Direct torque control technology is a kind of high static - dynamic state performance AC timing ways. This paper uses FPGA chip as the control core to design the induction machine direct torque control system and uses VHDL to program the system fuzzy control software. In the software, it studies 3/2 transform module, magnetic flux linkage and torque estimate module, M/T velocity measurement module, PI module, fuzzy control and start module , PWM module in detailed. Then it tests on the electrical machine platform and proved that the direct torque fuzzy control technology can make the induction machine the better performance.
