【Abstract】 In order to restrain the load disturbance and improve the dynamic precision of diesel engine speed regulation system,a controller for diesel engine speed regulation system with H_∞ control theory was designed,which transfers the specifications of system into a standard H_∞ control problem.The computer simulation result showed that the H_∞ speed governor would improve the dynamic precision of system and the ability to restrain the load disturbance in case of considering system model uncertainty,which improves the frequency stability of ship power system.更多还原
