Expected prior knowledge:

SC42015, SC42000 or similar.
Knowledge of classical control techniques (systematic and realistic PID design, frequency domain approaches) as well as state space theory is required.

Course Contents:

Computer control. Sampling of continuous-time signals. The sampling theorem. Aliasing. Discrete-time systems. State-space systems in discrete-time. The z-transform. Selection of sampling-rate. Analysis of discrete-time systems. Stability. Controllability, reachability and observability. Disturbance models. Reduction of effects of disturbances. Stochastic models. Design methods. Approximations of continuous design. Digital PID-controller. State-space design methods. Observers. Pole-placement. Optimal design methods. Linear Quadratic control. Prediction. LQG-control. Implementation aspects of digital controllers.

Study Goals:

The student must be able to:
1. describe the essential differences between continuous time and discrete-time control
2. transform a continuous time description of a system into a discrete-time description
3. calculate input-output responses for discrete-time systems
4. analyse the system characteristics of discrete-time systems
5. employ a pole-placement method on a discrete-time system
6. implement an observer to calculate the states of a discrete time system
7. apply optimal control on discrete-time systems
8. describe the functioning of the Kalman-filter as a dynamic observer

Education Method:
