Help Text for rotary actuator block
This block is the model of a rotary actuator.
The inputs to the block are:
- the controlled flows from the valve (is a two elements
vector) [m3/s]
- the external force acting on the actuator (a constant) [Nm]
- the torque transmitted by the a second mass connected to
the actuator output through a link, having a defined
stiffness [Nm/rad]
The input 3 shall be connect to the
output of a 'Stiffness & Inertia' block or to a 'Ground'
block if the second inertia is not present.
The outputs are:
- the actuator position [rad]
- the actuator speed [rad/s]
- the pressures into the two actuator chambers (it a two
elements vector) [Pa]
