1. A method for controlling process events of a technical plant, which comprises:

  • collecting variables relevant to a process;

    realizing a topology-maintaining nonlinear projection of data from the variables onto a multidimensional self-organizing neural map;

    displaying a trajectory of process events by connecting visualized process states graphically;

    displaying reference channels with adjustable tolerance widths on the map;

    evaluating the variables in relation to one another using the neural map;

    controlling process events in accordance with the evaluating step;

    evaluating sequences of process states using the reference channels;

    detecting if a trajectory deviates from one of the reference channels;

    evaluating a winner rate neuron representing a state; and

    bringing the process back into the reference channel.
