摘要：

This paper presents a detailed description of the electromagnetic actuator for active vibration control of a flexible rotor bearing system. The transfer characteristics of the electromagnetic actuator are investigated theoretically and experimentally. The linearized relationship of the electromagnetic force/input control voltage can be achieved by employing the analogue square root control circuits. A control algorithm which allows the control force of the actuator to be computed to minimize the synchronous rotor vibration is discussed. Computer simulation on a simple rotor bearing system is presented to demonstrate the effectiveness of the control algorithm in synchronous vibration reduction using the electromagnetic actuator.
