查询词典 experimental research

Direct Torque Control is a novel torque controlling technique which was proposed in 1980's. Although this technique has received a successful application in high-power ac drives recently, there are also a great deal of problems in the theories and practics which deserve to research. Centring around how to find and solve these prombles, theorical analyses, computer simulation and experimental studies are carried out in this dessertation.
