A study on high-speed and high-precision tracking control of large-scale stage using perfect tracking control method based on multirate feedforward control

In a control of hard disk drive, perfect tracking control (PTC) method has already gained high performance. Therefore, the first author and his group study PTC scheme for improving performance of large-scale stages. This paper presents an application of PTC scheme for two-types tracking stage. We compare performances of PTC method with a conventional method. Finally, the results of simulation and experiment show the advantages of PTC method which provides high performance.
