Help Text for single acting actuator block

This block is the model of a 3 position linear actuator. It shall be utilised together with its related control block: a command equal to 1 to the control block generates a displacement of the actuator to the maximum stroke position; a command equal to 2 produces a movement to the central position; a command equal to 3 generates a displacement of the actuator to the minimum stroke position.

The inputs to the block are:

  1. the controlled flows from the valve (is a two elements vector)
  2. the external force acting on the actuator (a constant) [N].

The outputs are:

  1. the actuator position [m]
  2. the pressures into the two actuator chambers (it a two elements vector)
