Abstract: This paper proposes a synthetical method of control system based on absolute stability for value-controlled hvdraulic dvnamic mechanism. This method is derived from nonlinear con-trol theory and the snecial condition of object system. The derivation,caiculation and simulation for a specific system are conducted.
