Help Text for 3 way proportional valve pressure regulated

This block is the model of a 3 way proportional valve, pressure regulated. The spool position of this valve is a function of both the input current and the controlled line pressure on the basis of the following relationship:

x = ki*i - kp*p

where

x is the spool position

i is the current

p in the pressure

ki is the current coefficient (can be different for positive or negative current)

kp is the pressure coefficient

The inputs to the block are:

  1. the valve current
  2. the system pressures, coming from the accumulator block (is a two elements vector)
  3. the actuator controlled pressure, coming from the single acting actuator block.

The outputs are:

  1. the valve input flows (is a two elements vector)
  2. the valve controlled flow
