Abstract

DTC (Direct Torque Control) with the torque and stator flux linkage as control variables directly, has the advantage of quick dynamic torque response, good anti-interference performance is also as an advantage, especially suitable for vehicle EPS power driven system to the requirement for the fast torque response ,and the SVPWM (Space Vector Modulation Sine Wave) compared with the traditional PWM modulation ,the SVPWM inverter modulation method has the advantages of high utilization rate in DC bus voltage and small harmonic components. So it has been widely used in speed control system. Based on MATLAB / Simulink simulation platform, using the DTC with a new simulation model of EPS permanent magnet synchronous motor vector control system driven with lower harmonic characteristics of SVPWM modulation method combining elaborated DTC PMSM mathematical model based on SVPWM control principle .A large number of experimental results shows that this method which based on the control of SVPWM vector control compared with the conventional torque control method has a good dynamic performance, small torque ripple, etc.It can be a proved effective and rational model for EPS driven motor control system, and also provides a theoretical basis and related reference for overall design .
