This paper describes my work on the design of digital tracking controllers over the past two decades. In tracking control, the control object must be moved along a time varying desired output and the transient path error must be minimized. Tracking control is discussed for the following two typical situations: one is the situation where the desired output is known in advance and the other is where the desired output itself is not known but has a certain known property, e.g., it is periodic with a known period. Control algorithms for dealing with these situations will be reviewed and applications to mechanical systems are discussed.
