Simulation of control of multi-variable control loop: steam turbine

Abstract

The paper deals with the description and simulation verification of one of possible methods to control of multivariable control loops. In this case, the so called main controllers, binding members and correction members are used. The proposed method of control combines classical way to ensure of autonomy of control loop via binding members and the use of the method of single-variable branched control loops with measurement of dominant disturbance variables to ensure of invariance of control loop via correction members. Main controllers can be proposed by arbitrary synthesis method. Simulation verifications of the control method are carried out for three-variable loop of a steam turbine.
