The Velocity Control System of Electromotor Based on the Software Phase- ]Locked Loop

With the development of the electric power and electronics, micro- electronics technology and control technology, the performance of electromotor timing syetem is required higher and higher, so phase - locked timing control has its unique advantage in steady speed precision . Based on the improved digital phase - locked loops , the paper puts forward the velocity control system of electromotor with the software phase - locked loops , and the Software phase - locked loops is achieved by use of high - powered microprocessor software.
