摘要： A method for wear-minimized operation of a component of an installation and a corresponding installation are disclosed. A sensor for state identification is associated with the component and transmits a sensor signal to an evaluation unit. The evaluation unit checks the sensor signal to ascertain whether a wear-promoting operating state is present, and in the event of the presence of such an operating state the component is driven such that a change in the operating state in favor of an operating state with less wear takes place. If, for example, a component is operated at its resonant frequency, it is ensured that the component is operated at a slightly different rotation speed, at which far less severe oscillations occur.

摘要： The invention relates to the online regulation of a batch process in a bioreactor. According to the invention, spectra of the actual charge in the bioreactor are recorded at successive points during the running batch process. A measuring vector is produced, for each spectrum, in the low-dimensional main constituent region by the main constituent analysis of the high-dimensional spectra. The deviation is calculated between the measuring vector and a corresponding vector of a nominal trajectory consisting of measuring vectors of a reference charge, which are determined in an earlier batch process, and at least one adjustment operation for the batch process is determined and carried out according to said deviation. The direction of the adjustment operation is maintained when the deviation determined from one point to the next decreases, and modified when the deviation determined from one point to the next remains the same or increases.

摘要： A method and device for controlling a self-regulating, delayed process, in particular a temperature control system, in which, after a first setpoint step change, the manipulated variable is set to its maximum value and an IT1 model of the process is identified on the basis of the step response. The time at which the manipulated variable must be reset for time-optimum control is calculated on the basis of this model. An additional, more precise model is determined if the rate of change of the controlled variable drops below a specific limit after the shut-off time. The parameters of a linear controller are set as a function of the more precise model, after which the controller controls the process in a non-linear mode. When additional setpoint step changes occur, a time for switching to a steady-state manipulated variable is calculated on the basis of the more precise model in order to achieve time-optimal control. The described control device adjusts to the process as early as after the first setpoint step change without requiring any knowledge about the process. The method and device may be used with adaptive controllers.

摘要： A control device for a process, in which a controlled variable can be influenced with the aid of a plurality of different regulating units, which in particular are based on different physical principles. A set point and the controlled variable are fed to both a first controller and a second controller. The first controller is located as primary controller in automatic operation and has a regulating range of the first manipulated variable that is defined by limiting values. The second controller can be switched between automatic operation and tracking operation, in which the controller generates a predefined or predefinable constant value of the second manipulated variable. By means of a logic circuit, the second controller is switched to automatic operation if a limiting value of the first manipulated variable is reached, and otherwise to tracking operation. Advantageously, by means of the control device, a plurality of regulating units which have the same direction of action can be operated fully automatically and autonomously.

摘要： For controlling multivariable systems, a control unit for controlling a system with several coupled control variables. The control unit includes controllers (10, 11) having associated control variables (x1, x2) as well as a decoupling network. The decoupling network is connected upstream from the system and includes at least one first decoupling member (12). A first output variable (y1) of a first one of the controllers (10) is routed to the first decoupling member (12). The first decoupling member generates a first correcting quantity (14) for a second output variable (y2) of a second one of the controllers (11). The second controller (11) has a PI- or PID-controller core (40) and is configured such that integrator windup is eliminated when the second output variable (y2) corrected with the first correcting quantity (14) reaches a manipulated variable limit. Bumpless manual/automatic changeover of the controller is also made possible.
