Help Text for rotary actuator block

This block is the model of a rotary actuator.

The inputs to the block are:

  1. the controlled flows from the valve (is a two elements vector) [m3/s]
  2. the external force acting on the actuator (a constant) [Nm]
  3. 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:

  1. the actuator position [rad]
  2. the actuator speed [rad/s]
  3. the pressures into the two actuator chambers (it a two elements vector) [Pa]
