Description

technical field [0001] The invention relates to a linear displacement sensor, in particular to a linear double redundancy sensor. Background technique [0002] The rapid development of unmanned aerial vehicles requires its control system to have high precision, high sensitivity and high reliability. The electric steering gear in the servo action system is one of the important components of the station flight control system, and it has been widely used. The power and static characteristics of the steering gear directly affect the control performance of the flying clamshell. Sensors are an important part of electric steering gear. It is difficult for the traditional single rudder loop sensor to make new breakthroughs in task reliability. Therefore, a high-performance sensor developed for the high reliability requirements of UAVs on steering gears can make the steering gears of UAVs reach The linear displacement sensor of the servo performance index is very necessary.
