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
