  5. Direct Torque Control

  6. DTC has 25 microsecond control loop Traditional PWM: • Control in short steps to avoid overshooting • Control loop time 1-3 ms because of modulator Frequency reference V/F ratio Modu-lator V AC f • Vector control: • Tachometer feedback required • Control loop time 1-3 ms because of modulator Speed control Torque control Modu-lator V AC f T • DTC principle: • Torque controlled by a single step • No risk of overshoot with fast 25 s control loop Speed control Torque control AC • Backlash appears in gearboxes and couplings. In backlash range motor may accelerate leading to backlash impact. Fast DTC control limits impact. • Mechanical resonances often appear due to elasticy of shafts and inertias of motor, gearbox and driven machine. Fast DTC attenuates the resonances.

  7. SwitchingLogic Torque and Flux Comparator Torque Reference Controller Torque Reference = Speed control PID ~ REF Speed Reference Torque and Flux Switchpositions Voltage Current Motor Model 3~ DTC CORE Calculated Speed Direct Torque Control • Advanced drives control

  9. Direct Torque Control increases drive performance • Advanced drives control Fast Torque Step Rise Time High Dynamic Speed Accuracy Torque Torque Open Loop DTC Speed Closed Loop Flux vector Speed error Open loop DTC 0.4 %sec Open loop flux vector 3.0 %sec Closed loop flux vector 0.4 %sec Open loop DTC < 5 msec Open loop flux vector > 100 msec Closed loop flux vector 10 to 20 msec

  10. DTC, Less stress to mechanics • Backlash appears in gearboxes and couplings. In backlash range motor may accelerate leading to backlash impact. Fast DTC control limits impact. • Mechanical resonances often appear due to elasticity of shafts and inertias of motor, gearbox and driven machine. Fast DTC attenuates the resonances.
