碩士 === 國立交通大學 === 控制工程系 === 85 === This thesis presents a hardware circuit architecture of a fully digitalvector control IC for ac servo motor using the field programmable gatearray (FPGA). The modular design approach has been proposed to simplifythe design and realization. The vector control IC for ac servo motor namedDMC-3000 can be used for the vector control of both permanent magnet syn-chronous motor and induction motor. The constructed IC consists of three major parts: a current vector control module, a decoupling control module,and a servo loop module. Specifications of the DMC-3000 are determined based on practical application considerations. Bit length effect of thecontrol IC has be或寫入converter and position feedback from the quadrature encoder can be directlyinterfaced to the develope motor control IC. The DMC-3000 can be incorporatedwith a digital signal processor (DSP) or a microprocessor to provide asimple solution for ac servo motor control. The control and status registersof the DMC-3000 can be on-line adjusted or monitored. A rotor-flux angleregister has been designed in the proposed DMC-3000, therefore, the flux model for the decoupling control of an induction motor can be easily realizedby it''s coprocessor. About 25000 gate counts are used to realize the proposedcontrol scheme. Experimental results have been given to verify the design and implementation of the proposed control IC.
