... The goal of this course is to teach some basic methodologies for analysing problems of control of partial differential equations. ... When dealing with controllability problems, one has to distinguish between finite-dimensional systems modelled by ordinary differential equations and infinite-dimensional distributed systems described by means of partial differential equations. Most of this course deal with problems related with partial differential equations. ...

... I do have a problem with the realtime capabilities of Linux. I wrote a loadable driver which uses the RealTimeClock to generate periodic interrupt at a frequency of 1024Hz. With each interrupt the driver increments an internal counter. The 'read' function of the driver returns simply that counter. Next I wrote a realtime task (with the highest priority) which read that RTC continuously. This tasks checks if the read counter is incremented by one between two read calls. ...
