Clustering Techniques for Stable Linear Dynamical Systems with applications to Hard Disk Drives
Nikhil Potu Surya Prakash, Joohwan Seo, Jongeun Choi +1
In Robust Control and Data Driven Robust Control design methodologies, multiple plant transfer functions or a family of transfer functions are considered and a common controller is…
Data-Driven Track Following Control for Dual Stage-Actuator Hard Disk Drives
Nikhil Potu Surya Prakash, Joohwan Seo, Alexander Rose +1
In this paper, we present a frequency domain data-driven feedback control design methodology for the design of tracking controllers for hard disk drives with two-stage actuator as…
Data-Driven Strictly Positive Real System Identification with prior System Knowledge
Nikhil Potu Surya Prakash, Zhi Chen, Roberto Horowitz
Strictly Positive Real (SPR) transfer functions arise in many areas of engineering like passivity theory in circuit analysis and adaptive control to name a few. In many physical sy…
System Identification in Multi-Actuator Hard Disk Drives with Colored Noises using Observer/Kalman Filter Identification (OKID) Framework
Nikhil Potu Surya Prakash, Zhi Chen, Roberto Horowitz
Multi Actuator Technology in Hard Disk drives (HDDs) equips drives with two dual stage actuators (DSA) each comprising of a voice coil motor (VCM) actuator and a piezoelectric micr…
