Abstract:
A control method is provided for using a feed forward technique. The method includes, but is not limited to using a setpoint value of a controlled variable to calculate a compensation of the closed loop static error, summing said contribution to the setpoint value, operating an estimation of the closed loop error to obtain a feed forward contribution.
