Application of photoelectric rotary encoder in flight simulation servo system

A new designing scheme of applying photoelectric rotary encoder to flight simulation servo system is introduced,and a realization method of servo system is proposed. The coding arithmetic principle of photoelectric rotary encoder is explained,then a fourfold-frequency direction-judgement circuit is designed. A triple close-loop control scheme is adopted in the flight simulation servo control system. The testing results show that the flight simulation servo systems which are adopted the proposed photoelectric rotary encoder and its related fourfold-frequency direction-judgement circuit can achieve a high control precision,excellent stability and strong robust.
