A control system and method for a controlled object in a time-variant system with a dead time, a single crystal - production device, for example, by the czochralski - the method

摘要

A control system for a controlled object (200) in a time-variant system with a dead time comprising:a memory means (104a) providing a set value (r) for an initial value of the controlled object (200) and a plurality of preset the system parameter values, which a plurality of system parameters of the controlled object (200), and which is configured in such a way that all or some of the plurality of the preset the system parameter values specific time variant characteristics have;a state - predictor (206) which, on the basis of the preset the system parameter values in said storage means (104a) are stored, and an output value in the case of a predetermined point in time and one input value (u_T) in the past history of the controlled object (200) the value of the specific state variables (x), which contains the initial value, at a future point in time (t + l) predicts the exactly by the dead time later than the present; anda float mode - control unit (212) which, on the basis of the desired value (r) on the future point in time (t + l), which in the storage device...
