FAULT TOLERANCE OF THE GAS TRANSPORT PROCESS BASED ON THE RECONFIGURATION OF REGULATORS

The issues of the organization of fault-tolerant control of the gas transport process are considered. The relevance of the issues of ensuring fault tolerance is associated with the need to improve the security of the process. The main attention is paid to the development of a model of the gas transportation process. The approach to model construction proposed in this paper is based on the Eickhoff concept, which considers the signal level of the model (responsible for converting input effects into output) relatively independently of the parametric one (responsible for the actual parameters of the transformation). The article also demonstrates the principles of constructing a process model based on typical energy cells. Typical energy cells are the basis for constructing a topological model of the first rank of uncertainty M(1). The construction of the signal graph of the integrated model in the form of a set of elementary cells, i.e. an integrated topological model of the first rank of uncertainty M(1) corresponding to elementary energy phenomena, allows forming the matrix of the integrated model as a block one. In this case, individual blocks will correspond to elementary interactions of the same type (thermal, gas-dynamic or kinetic). Based on this approach, a model of a gas pumping unit (GPA) is constructed. A feature of this approach for constructing a gas transportation model is to obtain a model in the form of a state space.
