Integral Feedback

The algorithm of structural and parametric synthesis of automatic control systems for limitedly uncertain non-linear objects with unstable balance status and right own values in their exit matrix is proposed. The pecu-liarity of the structural synthesis algorithm is that synthesized automatic control systems use differential com-pensating connection with two components. The signal of one of them is proportional to the signal of disa-greement between the required and measured values of the state vector of the system. A signal of another com-ponent is formed by the sign-operated integral feedback on the module of the control influence. The algorithm of parametric synthesis is reduced to solving the problem at a conditional minimum of integral regulatory error when limiting the characteristic frequency multi-member module to an algorithmically linearized system.

Working Out

This paper concerns two power stations using a combined thermal cycle where the heat of the exhaust gases is recovered in a boiler which delivers superheated steam to a steam turbine. After a description of the start-up process, it deals with a few typical problems which had to be solved in working out the automatic and semi-automatic control systems. It also describes auxiliary elements such as the control panel and the supervisory system. The choice between automatic and semi-automatic plants is discussed.
