Possible solution of decoupling and invariance of multi-variable control loop by using binding and correction members

Abstract

The paper describes one of possible methods how to control of multi-variable control loops. In this case the used method of control uses the so called main controllers, binding members and correction members. This control method combines classical approach for ensuring decoupling of multi-variable control loop by means of binding members and the use of the correction members for ensuring invariance of multi-variable control loop by means of two approaches. Main controllers can be proposed by arbitrary single-variable synthesis method. Simulation verification of the used control method is carried out for example of threevariable loop of a steam turbine.
