基于旋转变压器及TMS320F28035的伺服系统位置检测

为检测伺服系统位置信息，以旋转变压器作为位置传感器，设计了基于芯片AU6802N1的位置检测电路并在此基础上提出了一种仅利用TMS320F28035对旋转变压器转子位置直接解算的方法。该方法综合运用正弦峰值采样、CLA浮点数计算、误差校正等手段。实验表明，该方法在位置解算的速度和精度上可与AU6802N1芯片相比，节约了系统成本，具有一定的实用性。

Position Detection in Servo System Based on Resolver and TMS320F28035

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.
