Clustering Techniques for Stable Linear Dynamical Systems with applications to Hard Disk Drives

no code implementations17 Nov 2023 Nikhil Potu Surya Prakash, Joohwan Seo, Jongeun Choi, Roberto Horowitz

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 designed such that all the plants that fall into this family are stabilized.

Data-Driven Track Following Control for Dual Stage-Actuator Hard Disk Drives

no code implementations3 Apr 2023 Nikhil Potu Surya Prakash, Joohwan Seo, Alexander Rose, Roberto Horowitz

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 a part of the open invited track 'Benchmark Problem on Control System Design of Hard Disk Drive with a Dual-Stage Actuator' in the IFAC World Congress 2023 (Yokohoma, Japan).

Adaptive Model Predictive Control of Wheeled Mobile Robots

no code implementations3 Jan 2022 Nikhil Potu Surya Prakash, Tamara Perreault, Trevor Voth, Zejun Zhong

In this paper, a control algorithm for guiding a two wheeled mobile robot with unknown inertia to a desired point and orientation using an Adaptive Model Predictive Control (AMPC) framework is presented.

Data-Driven Strictly Positive Real System Identification with prior System Knowledge

no code implementations12 Oct 2021 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.

Adaptive Feedforward Reference Design for Active Vibration Rejection in Multi-Actuator Hard Disk Drives

no code implementations12 Oct 2021 Zhi Chen, Nikhil Potu Surya Prakash, Roberto Horowitz

In December 2017, Seagate unveiled the Multi Actuator Technology to double the data performance of the future generation hard disk drives (HDD).

System Identification in Multi-Actuator Hard Disk Drives with Colored Noises using Observer/Kalman Filter Identification (OKID) Framework

no code implementations25 Sep 2021 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 micro actuator (MA) operating on the same pivot point.
