碩士 === 國立臺北科技大學 === 機電整合研究所 === 96 === In this thesis, we use the hardware description language to code the hardware architecture, and the cell-based digital IC design flow is used to design the motor control IC of Direct Torque Control (DTC) system. The principle of the DTC system is to detecte the three-phase voltage, three-phase current, and rotor’s speed for calculating combination flux, combination flux position and motor’s torque. Then it properly chooses switch state of inverter appropriately to get a stable speed response. We apply the concept of fuzzy control to design proportion-integration controller. According to the feedback speed, the controller will change parameters to improve speed response time. We employ hardware description language to code the system function and then examine the functionality work. The ASIC implementation platform with TSMC 0.18μm library, Synopsys software and Candence software are employed for circuit implementation. The functions of the software include circuit compiling, auto routing and design verification for chip implementation. Finally, we have complete the design and implementation of the DTC system chip design for induction motor.
