| Summary: | 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.
