News Academy of Engineering Sciences A.M. Prokhorov Annotation << Back Methods of synthesis of logical-dynamic systems with the selector of control channels Petunin V.I. the features of the construction of automatic control systems (ACS) for complex technical objects, in which the number of control actions is less than number of controlled variables. It is shown that such systems are used to generate control logic elements - algebraic selectors signals (AS), which causes ACS to consider these as logical-dynamic. In ACS with the AS structure and dynamic characteristics of the controlled object are usually different for individual channels. This leads to the fact that the structure and parameters of the controllers in different channels at the input or output of AS will be different. Shows the effect of the dynamic characteristics of the control object to switching modes such systems. Consequently, there is a need to adapt the logical-dynamic automatic control system from AS to switch modes, channels to changes in the structure of the system. Therefore, the paper solves the problem of synthesis of logicaldynamic systems, automatic control gas turbine engines with a selective choice of channels by the quality of transients. The problems of the synthesis of different variants of ACS with the AS on the basis of which the principles of harmonization and adaptation of control channels. The results of the simulation. In conclusion, the application of the methods considered the synthesis of logical-dynamic automatic control system with speakers allows for seamless switching of channels and the quality of a given transition. It is shown that the results obtained can be used in automatic control of aircraft to limit the limit values of the object management. Key words: automatic control system, complex technical objects, the selector of control channels, logical-dynamic system, synthesis, transients, the results of the simulation.
