Abstract

This paper establishes the mathematical model of direct torque control (DTC) system of induction motor. Then a realization scheme of fully digitized direct torque control system is introduced with the DSP TMS320F2812 that works as the core control chip and IPM that works as main circuit. The control scheme obtains the switch control signal of inverter with the space voltage vector modulation technology. The system hardware and software structures are presented in this paper. The test results show that the DTC with SVPWM has many merits such as simple realization, good running performance and high voltage utilization ratio.
