碩士 === 國立臺北科技大學 === 電機工程系所 === 94 === The research of the thesis is based on the Hardware Description Languages (VERILOG). In order to implement the Direct Torque Control ASIC, the cell-based digital IC design flow is used to design the motor control IC. The basic principle of the Direct Torque Control is to select the switching state of the inverter. Those switches will control the magnetism and torque of the stator, respectively, which induce a fast response to the induction motor. The d-q axle''s static coordinate, which is transferred from both the three-phase current and the three-phase voltage, is used to compute the stator’s magnetism and torque. By comparing with original values, those magnetism and torque will be calculated into new data. Then the switching table and the hysteresis controller are decided with new data to generate a voltage vector to control the stator magnetism and torque. First, the system function is programming with the Hardware Description Language (VERILOG). Then, we use the compiler to confirm the syntax of the VERILOG code. And that the synthesis tool, the auto place & routed, and the function simulation tool are used to verify the design results of the Direct Torque Control. Note that the TSMC0.35um library, the Synopsys software and the Candence software are used to implement the Direct Torque Control IC.
