Position Detection in Servo System Based on Resolver and TMS320F28035
MA Jun-hua · Light Industry Machinery · 2012
To detect position information in servo system,taking resolver as position sensor,this paper designed position detecting circuit based on chip AU6802N1 and on that foundation proposed a direct decoding method only using TMS320F28035.This method includes sine peak value sampling,CLA floating-point number calculation and error correction.The test results show that this method is comparable to AU6802N1 both in speed and accuracy and can be used in practice to save system cost.
