Fluidized bed drying is a very effective method for fine materials. It provides intensive heat and mass transfer, which allows achieving high productivity. The introduction of automated control systems plays a key role in achieving stability of technological processes. At the same time, the fluidized bed itself is a dynamic system where the behavior of the material depends on many factors such as air velocity, particle size, humidity and temperature. This makes process control difficult, as even small changes in one parameter can lead to significant changes in others due to the existing cross-couplings. This work is a generalization in planning the methodology for synthesizing ACS by the process of drying sunflower seeds in a fluidized bed grain dryer, which is a complex dynamic multidimensional object with a delay. Moreover, the synthesis stages take into account the design features of the dryer, its operation in various modes, in particular in the stabilization mode, and the situation with the inability to fully measure the output signals of the object.
