Calculation of Discrete Automatic Control System fot Gas-Liquid Separator with Digital Regulators

Annotation The master's thesis includes an introduction, the main part, consisting of four chapters and a conclusion. The introduction is devoted to the discussion of the urgency of the problem, formulated the goal and lists the tasks that must be solved to achieve it. The first chapter provides information on the process of low-temperature gas separation, gives the main characteristics of the gas composition, the scheme of the installation with a description of the processes occurring in it, the principle of the separator. In the second chapter, a model of a multiply connected object - a gas separator is compiled. In the third chapter, the transfer functions of the control object are derived and structural diagrams are constructed. The fourth chapter shows the calculation of a discrete automatic control system. The system is calculated with various digital regulators and regulators of finite duration. Transient processes are constructed and quality indicators for each of them are calculated. The Conclusions formulate the main results of the work.
