| Abstract:Aiming at the electro-hydraulic driven exhaust valve control system used on marine low-speed diesel engines, the flexible control requirements of the exhaust valve were analyzed. On this basis, the functions of the whole control system were determined, mainly including:monitoring, analysis and processing of input signals; calculation of opening and closing angles of exhaust valve and output of control signals. The exhaust valve control model was developed based on Simulink software, and the function of the control model was verified by simulation. The verification results show that the exhaust valve control system model can realize the opening and closing control of the exhaust valve, and can automatically adjust the opening and closing angle of the exhaust valve according to the load of low-speed engines. |
