A method for regulating a istzuges to a desired tension by means of a by means of a model of the zugregelstrecke adapted tension controller

摘要

While a rolling stock (1) a by a front conveying element (3) and a rear conveying element (4) limited path section (2) with a rolling stock speed (v) passes through, it is with a actual tension (z), which to a desired tension (z *) is to be controlled. The actual tension (z) and the desired tension (z *) are fed to a tension regulator (5). The tension regulator (5) is an adaptation coupling (5 '') arranged upstream of the zugregelstrecke, by means of which, in a function of static and dynamic data of the rolling stock (1) and of the conveyor elements (3, 4), a dynamic current regulator characteristic (p, t) for the tension regulator (5) is determined. The current regulator characteristic (p, t), the tension regulator (5) is preset, so that the tension regulator (5) on the basis of the istzuges (z) and of the desired train (z *) in conjunction with the current regulator characteristic (p, t), a correcting variable (s) for a the actual tension (z) and adjusting element is determined and the manipulated variable (s) outputs to the actuating element. The adaptation coupling (5 '') comprises a first evaluation block (7), by means of the parameters (po, to, v, a_i, b_i, A_i, B_i) to be determined which an optimum regulation characteristic (po, to) describe or on the basis of which in connection with a predetermined determination prior publication, the optimum regulation characteristic (po, to) is determined, in which the tension regulator (5) control deviations, for example, an abrupt change of the desired train (z *) – with a defined transient response time corrected. The adaptation coupling (5 '') determines the current regulator characteristic (p, t) as a function of the optimum regulation characteristic (po, to).
