The BIVAL method
* ALPHA at format (F8.4)
PS=0.5
* K Ti Td N at format (3(F8.2,1X),F8.2)
PS=0.23 1245.2 0.00 5.00
ALPHA is the weighting coefficient between Z(1) and Z(2):
Y1(1)=ALFA*Z(1)+(1-ALFA)*Z(2)
On this variable Y1(1) we then apply a PID controller with the K, Ti, Td and N provided coefficients.
