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…
Adaptive Feedforward Reference Design for Active Vibration Rejection in Multi-Actuator Hard Disk Drives
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). This technology will equip drives w…
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…
A Highway Toll Lane Framework that Unites Autonomous Vehicles and High-occupancy Vehicles
Ruolin Li, Philip N. Brown, Roberto Horowitz
We consider the scenario where human-driven/autonomous vehicles with low/high occupancy are sharing a segment of highway and autonomous vehicles are capable of increasing the traff…
Employing Altruistic Vehicles at On-ramps to Improve the Social Traffic Conditions
Ruolin Li, Philip N. Brown, Roberto Horowitz
Highway on-ramps are regarded as typical bottlenecks in transportation networks. In previous work, mainline vehicles' selfish lane choice behavior at on-ramps is studied and regard…
