ASE-1258 Introduction to Control, 4-6 cr
Additional information
The extensions to give 5cr or 6cr are especially for 1) exchange students whose home university requires more than that available for 4cr, 2) international degree students who want to have a minor in Automation and Control, Robotics etc. Topics 13-16 form Extension Part D for +1cr. Extension Part E for +1cr includes Topics 17-20 and uses matrix skills. Registration to the extensions ar required during, not before, the course. The course may be preceeded by a voluntary pre-work for extra points.

Sub-Exams A-E of Parts A-E are called Tests A-E. A Total Exam may replace only the union of Tests A-C while exam questions of the extensions D-E can only be examined in Tests D-E. Option ABC of 4cr: A practical lab work & PC sessions A-C & Tests A-C (or a Total Exam). Option ABCD of 5cr: A practical lab work & PC sessions A-D & Tests A-D (or a Total Exam plus Test D). Option ABCE of 5cr: A practical lab work & PC sessions A-C and E & Tests A-C and E (or a Total Exam plus Test E). Option ABCDE of 6cr: A practical lab work & PC sessions A-E, Tests A-E (or a Total Exam plus Tests D-E) ). |

Learning Outcomes
After the course the student knows the potential and limitations of decision & control both within and beyond control engineering; knows typical control structures as well as connections and the roles nature of the control system components; can derive and approximate simple dynamical models in time domain. For LTI (Linear Time Invariant) systems: can derive transfer functions and state space models; can simplify block diagrams and perform model conversations; masters typical system terms and concepts including performance specifications; is able to describe and analyze control systems and other dynamical systems; understands and can analyze and even limitedly design stability, damping, accuracy and speed of systems with standard methods; is able to analyze potential stability and performance risks due to uncertainty and protect the system against them; masters a few synthesis and design techniques; can exploit use Matlab, Simulink, Control System Toolbox and Symbolic Toolbox or another similar enough software in the tasks mentioned; is able to communicate on the things with students and engineers educated elsewhere.

Instructions for students on how to achieve the learning outcomes
Please repeat concepts like limit, derivative, integral, complex number, vector, matrix, rank, inverse matrix, determinant on your own time or in the sessions organized by the teacher. Ask the teachers to help when relevant. Work 8-10 h for each topic and prepare yourself to the work sessions in advance as proposed in the instructions. Participate in Topic Exams. If it is not possible use SubExams as a 2nd plan. Try to avoid the need of a single Exam on all the topics in a session!
