Stewart Platform

[hfmvdl]

Does anyone have LabVIEW code to control a MOOG 6-axis Stewart Platform motion base?  It's a synchronous (60 Hz) TCP/IP packet interface to the low-level controller of our 2000E system.  We are building up a complete PXI-based control and data acquisition system for studies in rehab and biomechanics at UBC;  this piece would help us greatly get started. Thanks for any help you can provide.

I am involved in to the mathematical modelling of stewart platform.right now i m doing closed loop controlling usin PID in FPGA.I am also trying to do pid for all actuator simultaneously using multi channel PID (express VI of FPGA).If you want more then i can explain it.can u share ur objectives with the SP.

Pratsha,

Yes, I'd be very interested to hear more about your work.   Do you have a more detailed description of it?

Since my post of last year, we now have a fully functional interface for host/PXI-control of the 2000E base, including data capture from other sensors.  So far, we have no closed-loop control, just downloading ride files and controlling the base with a 6D joystick.  Being able to control everything from the PXI could be a very interesting prospect.
