Stability of Digital Regulators with Network Delivery of Controlling Variables
Abstract
Purpose: In this work, we develop a method of synthesizing automatic digital systems which would take into account the network delays of the controlling variables during their transfer to the digital corrector insensitive to their desappearance (because of loosing network frames) or late delivery. Results: A method has been developed to synthesize automatic digital systems with network delivery of controlling variables for which the maximum frame delay is defined for a given network environment. Taking into account the network delays allows us to compensate their influence on dynamic characteristics of the system by modifying its available part and using it at the next step of the synthesis. Due to this procedure, we can avoid using various predictors and compensators to ensure stability. The proposed method of digital corrector design provides its insensitivity to the loss of a certain number of network frames. For the software implementation of the model, Simulink package was used along Stateflow tool. Practical relevance: The obtained results allow you to take into account the delays and losses of network frames during the synthesis and design of automatic digital systems.Published
