# Problem 2 - Actuator block

From MurrayWiki

** Q** What are the dynamics that should be used for the Actuator block in Problem 2?

**A** For this simplified model, one can just assume that the actuator is static, and can be modeled as a scaling factor: you can just set it to be the identity map.
