发明名称 Method and control arrangement for controlling sheet-making process
摘要 The invention relates to a method and an arrangement for controlling a sheet-making process. In the solution, a sheet matching desired values is manufactured. A measuring unit measures the state of the process to produce one or more measurement value representing the state of the process. A comparator compares each measurement value with a corresponding desired value and, on the basis of the comparison, forms an error representing the difference between at least one measurement value and desired value. A control unit forms at least two control action candidates based on the error using at least two process models, of which at least one is a perturbed process model. A processing unit forms one control action from the control action candidates, with which control action the sheet-making process is controlled to produce a sheet matching the desired values.
