Abstract :
In this paper, we present a new seek algorithm formulated by combining the time-optimal control and input shaping methods. The algorithm achieves near optimal bang-bang performance with minimal excitation of the resonance mode. The computation requirements are minimal, and therefore, the algorithm Is attractive for practical design and applications. We shall focus on the application of hard disk drives
