Abstract

Abstract The work focuses on the computer simulation modeling of the control system with the network channel of information transmission. We have studied the impact of data buffering on the quality of control for the systems with a limited volume buffer for data packets. It has been expected that the data packet transmission over the network channel for the quantization period is carried out with a given probability. If the data packet from the digital sensor is not transmitted in one quantization tact to the controller, it is placed in the sensor buffer. During data is transmitted over the channel, all packets from the sensor buffer are transmitted to the controller buffer. The controller processes incoming data from the buffer sequentially-one packet per quantization tact. To simulate such situations, it was proposed to use the appropriate developed random processes. The novelty of the developed simulation model lies in the fact that in the basis for the development of this model is accepted the modeling of the time gap of the information flow of data. Simulation of the network control system operation was carried out in the environment Simulink of Matlab system.
