Simscape: High priority position target not achieved
显示 更早的评论
I have two "actuators" which are connected to the cylinder. Cylinder is connected to Universal Joint which sets initial conditions (its orientation only). So whole system should act almost like a pendulum. Problem is that system works nominally when only Actuator II is present (right side of the model). However, when exact copy of it (Actuator I) is added to the model, system could not meet initial conditions, and could swing only in single plane (X or Y), and it can`t do "diagonal" movement. Even if only Actuator I is present, still the same problem occur. I have no idea what may caused such problem, because both actuators are similar to each other. Kinematics of the model should be valid.
I assume that either I did crucial mistake with rotational transformations or joint is not connected properly either solver configurations should be adjusted to be able to solve eq.
I have added test version of the model, so you could have a look.

In test_actuators/Engine+Actuator, replace Revolute Joint I and Revolute Joint II with Spherical Joints. You don't have enough degrees of freedom with revolute joints.
