Abstract
A control system is disclosed for a noninteracting control and protection of a dynamic compressor having rotating vanes. The method consists of a junction of a few control circuits for controlling the performance of a dynamic compressor, for protecting compressor from approaching dangerous zones of operation, and for maintaining a required mass flow rate of a gas through the compressor. An automatic control system based on using the above method is distinguished by its simplicity, great transient and steady state precision and high reliability of surge protection.
