Description

technical field [0001] The invention relates to a rudder deflection angle measurement system, in particular to a dynamic high-precision grating ruler rudder deflection angle measurement device and a measurement method. Background technique [0002] Missiles are an important weapon in modern warfare and an important symbol of national defense modernization. Modern warfare puts forward new requirements for the development of guided weapons, requiring missiles to strike targets accurately and quickly. Therefore, missiles must be precisely controlled during their flight. [0003] The steering gear servo system is an indispensable part of the missile system, which controls the flight trajectory and flight attitude of the missile. When the system is working normally, the steering gear controller receives the rudder surface deflection angle signal given by the guidance computer, and at the same time controls the rudder surface deflection according to a certain algorithm to ensure ...
