CMC Failure
Posted: Wed Apr 22, 2009 8:49 pm
I am running a jumping data set to run through RRA and CMC. After I change kp and kv to 2000 and 100, it went through without problem. I compared the original data with RRA's results and they seem to match pretty well. However, the CMC failed every time even after I modified kp and kv to 2000 and 100, and the optimal_force to 50 of reserve in the actuator file. It failed at the very first frame of simulation with the following error message:
SimTK Exception thrown at InteriorPointOptimizer.cpp:249:
Optimizer failed: Ipopt: Restoration failed (status -2)
OPTIMIZATION FAILED...
rdCMC.computeControls: WARN- The optimizer could not find a solution at time = 1.121000.
If using the fast target, try using the slow target.
Starting at a slightly different initial time may also help.
I tried to to start at different time but still received the same fail message.
Any suggestions
