  abstract=      "Most motion control systems for mechatronic systems are
     implemented
on digital computers. In this paper we present
     an FPGA based solution
implemented on a low cost Xilinx
     Spartan III FPGA. A Production
Cell setup with multiple
     parallel operating unit is chosen as test
case. The embedded
     control software for this system is designed in
gCSP using a
     reusable layered CSP based software structure. gCSP
     is
extended with automatic Handel-C code generation for
     configuring the
FPGA. Many motion control systems use
     floating point calculations
for the loop controllers. Low
     cost general purpose FPGAs do not
implement hardware-based
     floating point units. The loop controllers
for this system
     are converted from floating point to
     integer-based
calculations using a stepwise refinement
     approach. The result is a
completely FPGAbased motion
     control system with better performance
figures than previous
     CPUbased implementations."
