    • The present invention relates to an arrangement for the discrete-time adaptive on-off switching control of a continuous-time process with a binary switching actuator, which uses for the determination of the on-off actuating signal a prediction of a process output sequence over several future sampling intervals as reaction to a possible process input sequence that is applied to a discrete-time linear process model and which estimates and updates in every sampling interval the parameters of the process model by means of a parameter estimation device in order to adapt them to the process to be controlled, even when the process behavior changes, and which has a device for the input and change of the setpoint, the limits of the process output and the sampling time as well as a measuring device for the periodical measurement of the process input. The arrangement further comprises two alternatively working control devices one of which is active in the stationary phase and the other of which is active in the start-up phase of the process or after setpoint changes, and a switching device which activates one or the other said control device in dependence of the result of the measurement of the process output and of input current setpoint, wherein the actuator is served by the active control device.
