Abstract: To control a technical system having multiple system components, multiple functional modules access a common data model. The functional modules in this case include an interface module, a simulation module and an output module. The data model includes data components associated with the system components and simulation model data for a simulation model of the technical system. The functional modules are actuated by a flow controller, wherein the flow controller and a respective functional module have functional-module-specific selection data transmitted between them that the respective functional module takes as a basis for accessing model data of the data model. The interface module continually captures operating data of the technical system and stores them in the data model by means of selection-data-specific access.

Abstract: Provided is a method for operating a system including components controllable by control variables, including the determining of at least one optimized control variable at an optimization period for minimizing or maximizing a target function of the system in such a way that at least one system variable fulfills predetermined secondary conditions with respect to the control period, wherein the determining includes the establishment of an evaluation function for each of the secondary conditions to evaluate a change of the system variable at the end of the optimization period based on a current value of the system variable at the beginning of the optimization period, based on a gradient of the system variable relating to the secondary condition and maximally achievable over the control period, and based on a gradient relating to the secondary condition and minimally achievable over the control period.

Abstract: Control apparatus and method for a sewage plant in which wastewater is nitrified and denitrified in an aeration tank by intermittent ventilation via a controllable ventilation facility, where the ammonium content of the wastewater is measured and the nitrification phase is terminated by switching off the ventilation if the measured ammonium content has dropped below a threshold value, where in order to improve control of the nitrification, the output of the ventilation facility is controlled within the duration between the start and the end of the nitrification phase as a function of the currently measured ammonium content of the wastewater and the threshold value.

Abstract: A process is disclosed for operating an industrial plant by means of a guidance system that controls processes in the industrial plant, in which process operation-relevant data such as states, malfunctions and/or degradation of devices of the industrial plant are acquired by an operator; the operation-relevant data are acquired in an operation monitoring system and stored in electronic, preferably standardized form, and operation-relevant data on events which can affect process control, such as malfunctions of devices, are electronically transmitted to the guidance system.
