Research on Surplus Torque in Passive Electric Loading System

A key difficulty in electric loading system is finding an effective method to eliminate the surplus torque and enhance loading precision.Based on the hardware structure and operation principle of the missile rudder electric loading system,the causation,mathematic model and test method of surplus torque are analyzed.The experimental results show that the proposed method is effective to eliminate the surplus torque,the air resistance when missile rudder is spreading is accurately and rapidly simulated.
