The paper deals with this problem of automatic control of the orthogonalization plants for textile industry by using a process computer. To do this an original mathematical theory of the textile threads correction phenomenon, particularly orthogonalization phenomenon is developed, as a ground for obtaining the mathematical model of the controlled plant. It is proven that the mathematical model corresponds to a nonlinear time-varying system with several time-delay variables with 2 inputs and 2p outputs, where 2p is the number of the slope transductors. It is pointed out the nonlinearity is a nondynamical one, which can be separated from the linear dynamical part. The control law algorithm which can be implemented on a numerical process computer is obtained. Several practical results obtained by simulation are presented.
