... the compressor based on a given safety margin to the surge and braking modes. Materials and methods Research were carried out on a computer using computational methods of nonlinear programming, including the method of least squares, penalty functions, Hooke - Jeeves, Pattern search. Results On the basis of the compressor's gas dynamic passport characteristics is made nonlinear mathematical model of the process gas compression in the compressor with regulating valve on the suction. The model includes ...
