This thesis proposed the design and implementation of an ASIC for the motor control with DTC technology. Note that this ASIC is implemented by cell-based Design style with Verilog language.The basic principle of the Direct Torque Control is to select the switch sequence of the inverter. Those switches will control the magnetism and torque of the stator, to induce a fast response of the induction motor. Furthermore, the d-q axle's static coordinate, which is transferred from both the three-phase current and voltage, is used to compute the stator's magnetism and torque. By comparing with original values, those magnetism and torque will be calculated and set to new data. Then the switching table and the hysteresis controller are decided with the new data to generate a voltage vector and to control the stator magnetism and torque.
