Abstract A high performance electromagnetic counter-force actuator is designedfor engine active vibration control system. Firstly, design requirement and structure principle of actuator are briefly introduced. Then, approximate calculation of its magnetic field is carried out. Transmission model of active force is simplified as a single free degree vibration system to calculate active force of actuator. Finally, active force is simulated with Simulink and performance experiment on active force is conducted by taking sinusoidal signal as input. The results indicate that this actuator can produce great force and has high performance, which is of great significance of the implementation of engine active vibration control system and development of other active control systems.
