碩士 === 國立臺北科技大學 === 機電整合研究所 === 92 === The main research of the thesis is based on Cell-based digital IC design flow. We use the way to design and make the motor control ic, the ic is Direct Torque Control ASIC. The method of DTC is analysis the mathematic model of induction motor on stator coordinate axis. We use the input voltage and current to control the torque and flux. It’s foundation on Space Vector Modulation. Therefore the DTC ASIC can control the signal by stator torque and stator flux then to bring the on and off signal. After the inverter we can control the induction motor immediately, and the control technology is better. The cost is less and less. First, the system function is programming in the Hardware Description Language（VERILOG）.Then, we use the compiler to confirm the syntax of the VERILOG code, After that, the synthesis tool , auto place & routed and function simulation tool are used to implement the design flow of the Direct Torque Control. We also can be implemented by Filed Programmable Gate Array（FPGA）in hardware. We use the FPGA to replace the design of DTC control IC. Adding the input signal control board by myself then cooperated with the power driver and the induction motor of the three-phase AC power. In the testing system, FPGA generate the control signal to drive the power driver successfully, and the power driver also makes the motor to rotate correctly.
