control

This paper discusses a discrete-time loop shaping algorithm for servo enhancement at multiple wide frequency bands. Such design considerations are motivated by a large class of practical control problems such as vibration rejection, active noise …

The importance of safe and flexible disturbance rejection at high frequencies has been ever increasing in modem control systems. For example, new applications of hard disk drives (HDD) require that the HDD control system be robust to (e.g., have the …
