Feedback Control Applied to the Nanopore

General Definitions:Feedback Control - a tool to make dynamic systems self-regulating (automated).

Control Logic - hardware/software that collects system measurements, and converts them into commands to influence the system.

Traditional Example: Cruise Control

System - the car

Measurement signal - car speed (V)

Command signal - throttle (T)

Objective - automate T so that V remains at a constant desired value (Vdes)

Control Logic - T = Tstat + Tdyn

Tdyn = a[Vdes-V ], a>0

too slow accelerate, too fast decelerate

Feedback Control Enables Self-Regulation

Feedback Controlled Nanopore: Automating Detection and Fast Voltage Reaction

Control logic programmed in a finite state machine (in SW), and implemented with a field-programmable gate array (HW).

Control Logic programmed using a Finite State Machine (FSM) in software

FSM made up of states, transitions between states, and actions.Cruise Control Revisited:

Control Logic: Tdyn = a[Vdes-V ], a>0 roadcar

Control Logic in an FSM:

States - status of V

Transitions - based on value of V relative to Vdes

Actions - assign a value to Tdyn for each state

Career and Internship Discussion

• Exit interviews– Students would like more career-fair

opportunities for engineers• The campus fair only attacts a handful of

technology companies

– Students would like more internships• Many graduate students find internships

through faculty connections• Fewer undergraduates do

Careers and Internships

• UCSC Career Fair in Silicon Valley?

• Career Mingles or Panels?

• Other enticements for companies?

Careers and Internships

• Formal Internship Programs– ISM/Seagate– CE/Cisco possibility– Other connections?

Careers and Internships

• Developing Faculty Relationships– Group company visits/research days?– SVC showcase?– Other ideas?
