Novel Hybrid Magnetic Helm Actuator of Micro-Aircraft

A novel magnetic actuator designed for a micro-aircraft is presented, it is an actuator helm of the hybrid magnetic. It possesses many characteristics of small size, light weight, rapid response, high reliability and so on. The design consideration is described. Mathematics model of magnetic act uator is established due to the relation of the attractive force and the inverse force. A control characteristic is introduced by analysis of the model. Experim ental results verify that the output performance of the magnetic actuator is lin ear and has a dynamic response.
