Angle sensor is the key equipment for servo control system to complete the position closed-loop and realize accurate measure. The output angle accuracy of sensor is very important for the system position control. A high precision angle sensor based on two-speed resolver is advanced. Working principle of twospeed resolver is expatiated using STM32 as the processing core. Scheme design and soft design are particularly introduced. The test results show that the angle sensor has extensive application future with accuracy up to 20".
