**Overview of course:**

The course gives an introduction to linear and non-linear systems analysis and control systems with biological and medical applications. The class starts with an introduction to modeling with examples taken from physiological, (bio)chemical, fluidic and electrical systems. The course then continues with a more general study of linear and non-linear systems using ordinary differential equations that includes for example a study of numerical methods, software applications, transfer functions, feedback control, transient and steady state responses, phase portraits, system linearization and chaotic systems. The course is motivated with examples taken from biochemical control, synthetic biology and physiological systems.

### Teaching Style

The individual lecture periods are a little long and are also over lunch break – the worst of two worlds. The teaching style for this class will therefore be a little different. If you wish you can bring your lunch with you to class. To break up the time, the class will be made up of segments of lecture and group exercises. Groups should be no more than three people and the exercises may involve problem solving, math problems or simulation on your personal computer. To make up for lost lecture time, online videos will also be posted for to watch as homework. The videos will be a combination of new videos and existing videos from the internet. The first ten minutes or so of every Tuesday will be reserved for a speed quiz which will be graded. There will be the usual mid term and final project at the end of term.

### Course Text Book

Control Theory for Bioengineers 0.57 (835)**Other Text Books for Reference:**

Circuits, Signals, and Systems for Bioengineers: A MATLAB-Based Introduction by Semmlow

This is has a reasonable straightforward introduction to linear control systems but the author places much emphasis on electrical systems.

Feedback Systems An Intro for Scientists and Engineers (Astrom and Murray)

This book offer a nice introduction to linear control systems and feedback specifically for scientists and engineers. It comes with examples taken from different areas include some biological. This book is also available for** free** in PDF format.
