Aerospace Instrument-Making Annotation << Back THE ESTIMATION INTERACTION OF PROCESSES IN THE CHANNELS OF CONTROL SYSTEMS BASED ON THE TAKAGI-SUGENO MODEL S.N. Chukanov Complex nonlinear dynamic objects are characterized by a high level of interaction of processes between subsystems. When designing a control structure for dynamic objects, measures of interaction between channels are traditionally used. It is possible to minimize the structure of the control system and simplify the design of the control system considering the interaction between the channels of the control system. The article proposes a method for analyzing the interaction of processes in control systems of complex nonlinear dynamic objects, which uses Takagi-Sugeno fuzzy model to identify the structure of the control system. An example the estimation of interaction of processes in the stabilization system of the components of the angular velocity vector of a solid is given. The method for evaluating the interaction of processes in subsystems of control systems using the Takagi-Sugeno fuzzy model can be applied in the design of complex systems. A quantitative account of the interaction of the channels of a complex control system allows one to form an artificial interconnection of the object’s movements, which increases the reliability of the system’s functioning while taking into account the use of analytical redundancy of information from various devices and, consequently, reduces the mass and overall characteristics of the systems.
