In this thesis, we try to implement TMS320C31 in a multiple
axes motion controller. This motion controller consists of five
modules, namely, CPU and peripheral module, communication
module, man machine interface (MMI) module, multiple motors
control module and pulse width modulation (PWM) module. The CPU
and peripheral module is the most important component of this
controller. Base on this module, other circuits were de-
veloped thereafter. The communication module includes an RS232
serial port, a 16 bits PC/AT ISA BUS parallel communication
port and a 24 bits general-purpose communication port. The MMI
module supports a set of LCD and a 5*5 keyboard for man-machine
communi- cation, if necessary. The multiple motors control
module receives motor feedback signals and generates driving
commands for motor control. The PWM module generates six phase
pulse width modula- tion signals to drive AC servo motors. In
order to reduce the complexity of the circuit and the size of
the board, some advanced, programmable integrated devices such
as PAL (Programmable Array Logic), GAL(Generic Array Logic) and
FPGA(Field Programmable Gate Array) are intensively implemented
in the design. After the system was designed and assembled, it
is thoroughly tested. The system has been proved to be able to
work as we ex- pected.
