Abstract:

Four different Anti G Valve Anti G Suit systems which include mechanical type,electrical type and mixed type,were investigated.Three dynamic models were developed through theoretical research and system indentification to describe the dynamic response of each kind of system.The relationship among three models'structure was also discussed.
