EL1000 Automatic Control, General Course
KTH Royal Institute of Technology
Knowledge in differential equations and transform methods, 5,5 higher education credits, equivalent to completed course SF1683/SF1692.
The course covers how feedback influences properties of dynamic system such as stability, speed of response, sensitivity and robustness. The course contains analysis and design of feedback systems with regard to these properties. In particular, the following is studied
- basic concepts and problems: application examples of automatic control, representation of dynamic systems, input and output signals, differential equation models, transforms, transfer functions, block diagrams, impulse response, step response, poles, zeros and linearisation
- analysis of feedback systems: stability, root locus, the Nyquist criterion, Nyquist and Bode diagrams, precision, speed of response, sensitivity and robustness
- design of control systems with one input signal and one output signal: specifications, PID-controllers, compensation in the frequency domain, feed-forward control, time delays, state feedback, observers and pole placement
- implementation: choice of sampling time, anti alias filters and discretisation of controllers
- control terminology in Swedish and English.
After passing the course, the student shall be able to
- formulate basic theory and definitions of important concepts in general automatic control
- apply analysis and design methods in general automatic control.
