SYNTHESIS OF SELECTIVELY INVARIANT CONTROL SYSTEMS FOR THE NATURAL GAS COMPRESSION PROCESS

A simplified model of a compressor line is considered, which includes a natural gas pumping unit and a network at its outlet. The goal of the gas compression process control is to ensure selective invariance – independence of the steady-state reaction of the system to specific types of disturbances. The synthesis of control systems is aimed at maximizing the frequency spectrum of attenuated disturbances while maintaining the aperiodic nature of the object dynamics. A compromise between the requirements for steady-state and transient processes is achieved by compensating for the dominant eigenvalues of the object. An evolutionary synthesis procedure in the frequency domain is presented in the form of a sequential formation of the causal topology of the system and control algorithms with subsequent optimization of parameters.
