General Information

Division: Automatic Control
Course type: Third-cycle course
Teaching language: English

Aim

The aim of the course is to give the doctoral student a good understanding for, and the solutions to the probelms that arise when continuous-time ststems och processes are regualted by discrete-time computers. The course provides the necessary insight, knowledge, and understanding required to effectively analyze and design computer-controlled systems

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• know how state-feedback controllers and observers can be designed for discrete time systems using pole placement, understand their properties.
• know, and understand the main properties of linear quadratic control design methods.
• understand discrete-time noise models.
• know how to obtain models suitable for design of computer-controlled systems, for instance by sampling analog system models, noise models and cost functions.
• know how to handle practical implementation issues such as limited bit-width and sampling rates.

Competences and Skills

For a passing grade the doctoral student must

• be able to design models and controllers suitable for computer implementation.
• be able to do calculations based on the Z-transform.
• be able to design controllers based on pole placement and linear quadratic methodology for discrete time systems

Judgement and Approach

For a passing grade the doctoral student must be able to critically judge the performance of different models and design methods for discrete time systems

Course Contents

Analysis of Discrete-Time Systems, Sampling, Z-transforms, State-feedback and observers, pole-placement, I/O-models, Delta operator formalism, implementation and noise models, Optimal linear quadratic control in state-space and I/O form
