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)=ALFAZ(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.
