The article describes the developed real-time operating system "VladOS," which is a set of modules and utilities from which the required system for controlling the eco-house should be assembled. Users can load their written applications into the file system in the form of binary files. System generation involves selecting an active configuration from a list of available user applications, setting values of system configurations, compiling system module parameters using this configuration, and linking system modules into an executable program.

Compressed air is an important medium for energy transfer in industrial processes. It drives various actuators, which create a large force for significant movements and a high operation speed. Thereat, these mechanisms are quite small, and the design is simple and reliable. They are applicable in food and pharmaceutical technologies. Compressed air systems belong to the largest energy consumers at such enterprises. They consist of several compressors, and the drive of one of them is powered by a frequency converter in order to save electrical energy.

Compressed air generation systems are a necessary facility for most enterprises; they also belong to the most energy-consuming equipment category. Study of transients of these systems’ operation is a prerequisite for creating new, more efficient algorithms of multi-compressor control systems. The paper presents the results of development and research of the operation algorithms of multi-compressor control systems.
