The segmentation fault is appearing less often. I made a mistake with the sign of the controller. However I still have doubt related to the actuator dynamic. I am inserting it correctly? I mean, should the model be inserted before the world_->integrate()
or inside its for loop?
Moreover, I am noticing a change of performance in my controller setting "PD_PLUS_FEEDFORWARD_TORQUE" with
Anyway, if I set:
And then:
setGeneralizedForce(tau)
is the same thing of do:
setPdGains(Kp, Kd)
isn't it?
from raisimlib.
No they are different. The PD controller is more stable because it is updated in an implicit manner. Its behavior is similar to having an infinitely small time step.
Check the states before it segfaults. If they are exloding, that means that your controller is not stable. Otherwise, try Valgrind following the instructions in the manual
from raisimlib.
Okay, I am figuring out that maybe I should use an explicit solver to improve sim-to-real.
Anyway, I am debuggin with valgrind as you suggested. It raises this error:
Does it depend still from my code?
from raisimlib.
That looks like an another issue. I'll look at it. But conditional jump should not trigger a segfault. There must be another error message, possibly related to the memory
from raisimlib.
