Aim
The aim of the course is to give a deeper knowledge and understanding for the mathematical theory behind many of the concepts and methods taught in the Basic Course in Automatic Control (FRT110)

Knowledge and understanding
For a passing grade the student must

understand the matematical definition of the Laplace transform and frequency response curves
understand the interpretation of the general solution to the state-space description as a mapping and how this can be used to define controllability and observability

Skills and abilities
For a passing grade the student must

be able to use the argument principle, the Nyquist theorem, and Bode's relations to decide stability and robustness
master the sensitivity functions and its properties
be able to use coordinate changes in state-space to show properties of zeros, state feedback, and observers
be able to use the relationships between different criteria for controllability and observability
be able to apply Kalman's decomposition formula in order to understand series connections, and cancellations and non observability in state feedback
be able to present concepts from automatic control on oral and written form

Judgement and approach
For a passing grade the student must

understand the value of mathematical reasoning as a tool for solving control problems
be able to grasp a mathematical proof as a part of understanding, e.g., the proof of the Nyquist theorem and Bode's relations
be able to discuss and present group work in the form of the solution to a hand-in problem

Contents
The course is given in parallel with the Basic Course in Automatic Control (FRT010). It brings up many of the concepts that are being taught in the basic course from a more mathematical perspective. Some examples are: Solutions to the system equations, deduction of controllability and observability criteria, Kalmans decomposition formula, the argument principle, robustness analysis.
