Abstract


A technique for the synthesis of hardware controls of the manufacturing processes parameters with specified accuracy and capacity has been developed on basis of the frequency characteristics method. The mathematical model of a computing unit in the form of an aperiodic circuit with delay is proposed for the first time. An information technology for analyzing the frequency characteristics of a control system with using the capabilities of the Matlab has been developed. An amplitude frequency characteristics, the Nyquist hodograph, transfer and pulse response transfer characteristics were obtained by computer simulations. Moreover the stability margin of the system by the amplitude was determined. It is proved that the application of developed techniques increases the productivity of the process of hardware synthesis.
