1. comprise the controlled variable that comprises input state and comprise the control system of device procedures of the control variable of output state, described system comprises:

  • Be used for measuring the sensor device of above-mentioned at least control variable;

    Store the upper and lower limit of at least one control variable and the memory storage of correction time constant, above-mentioned upper and lower bound limits this control variable can received scope;

    The processor device that links to each other with above-mentioned storage arrangement with the sensor device, it includes the data of the model of describing the said equipment process, described model makes the cost of controlled variable relevant with control variable, and provide predicted value for described at least one control variable according to finding the solution further, described processor device also comprises logic circuit apparatus, when the measured value of described at least one control variable is outside described bound, this logic circuit apparatus produces a signal, to obtain the described controlled variable of change on the direction of its least cost, described controlled variable changes in one direction so that the predicted value of described at least one control variable is within the described bound;

    In response to the control signal device of described control signal, it is used as the device of the described equipment of operation to control described controlled variable.
