Abstract
This paper introduces a resolver decoding circuit based on the position detection of a step-stare panoramic imaging platform. Through the use of AD2S1210(revolving transformer/digital converting IC produced by ADI), to decode the resolver J78XFS009, a decoding circuit is designed. The design includes the basic working of ADS2S1210, the interface circuit and the connecting circuit between the micro-controller and resolver and so on. The whole circuit has the advantages of simple structure, high reliability, working stability, high precision and better noise immunity, etc. It can be used under harsh environments, so it has high value of practical use. The experimental results show that the circuit can detect the position signals of the DC motor accurately, so it can contribute to achieve a more precise closed loop control of DC motors.
