A low-cost resolver position solving methods in servo system was analyzed and proved. First, in- troduced the basic principle of this method, including the resolver excitation generation, sampling synchroni- zation and the digital solving method of position and speed. In the experimental part, completed the relevant tests based on permanent magnet synchronous motor. The results show that the method has high-precision and high-response characteristics, can meet the dynamic and static performance requirements of servo system.
