Abstract

The application of the obtained control of multidimensional objects can be suboptimal under conditions of input coordinate uncertainty and can entail unacceptable process quality losses. To solve this problem, a suboptimal control searching method is proposed, which consists in building a control matrix from the input coordinate values, control actions, and control criteria, the distance between adjacent values of which ensures acceptable process quality losses. To reduce the volume oft he matrix elements under consideration at the stage of system design, it is proposed to carry out their preclustering. At the operation stage, for the measured values of the input coordinates, a cluster is sought with the nearest center, among the elements of which a vector is selected from the control matrix in terms of the smallest distance. In the context of a galvanic chrome coating of crankshaft pins, the effectiveness of the method developed is shown.
