Abstract
The invention relates to a method and a controller for controlling a process. The process output signal or the control output signal comprises a functional variable and the process output signal is defined for at least one moment of time. The controller performs a functional operation on the signal comprising the functional variable to preserve the functional information. The controller also forms a cost function of at least the signal comprising the functional variable with the preserved functional information and performs an optimization of the cost function in which the preserved functional information is included. Finally, based on the optimization of the cost function the controller forms at least one process input signal for at least two separate moments of time for controlling the process.
