Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

Mathematical concepts that the student must master before starting the course are:

- Complex numbers
- Linear algebra
- Taylor expansions
- Ordinary differential equations

It is also assumed that the student has basic knowledge about the fundamental physical relations that are necessary to formulate energy, force and material balances.

Aim

The aim of the course is to help mechanical engineering students to understand how control might be used to develop and implement control function for mechanical systems. Furthermore the aim of the course is to widen the student s perspective on technical systems by understanding how mechanics, electronics, computers, and control interact and how this might be used to improve and develop new products that offer new functionality and increased performance.

The course uses knowledge from the fundamental courses in mathematics, mechanics and computer programming and will prepare the student for further studies in subjects where fundamental knowledge in dynamical systems and control engineering is required.

Learning outcomes (after completion of the course the student should be able to)

show basic knowledge in control engineering analysis and design methods. This knowledge could be used to systematically solve basic control problems. More specifically, the student should be able to:

Define the control problem. Define feedback and feed forward. Describe and explain the most important properties of linear systems. Understand how the frequency content of a signal could be analyzed.
Formulate a dynamic model for basic mechanical, electrical and chemical systems. Explain the possibilities and limitations of state-space models and transfer functions. Transform between state-space models and transfers functions, when possible.
Compute linear approximations of non linear models and understand the limitations of the non-linear model.
Analyze the stability properties of linear dynamic systems and analyze the closed-loop systems stability properties based upon the Nyquist-criteria.
Understand how feedback and feed forward can be used to decrease the influence from process- and measurements disturbances and parameter variations in the controlled process, and also understand the limitations of feedback and feed forward.
Design controllers that fulfills given specifications given as performance, robustness- and stability margin requirements. Analyze and evaluate different controller structures, mainly P, PI, PD, PID and state-feedback controllers.
Implement the designed controller in a computer and understand sampling and its consequences.
Use modern computer tools to facilitate analysis, design, and evaluation of dynamical systems.

Content

Introduction: Examples of control problems, dynamic systems, feedback and feed-forward, compensation of parameter variations, process and measurement disturbances.

Fundamentals of signal theory: Frequency analysis of signals.

Dynamic models: Differential equations, Laplace transforms, transfer functions, block diagrams, impulse response function, frequency response, transient and frequency analysis, Bode diagrams. Principles for building dynamic models for engineering systems. State space models, non-linear systems, linearization.

Analysis of feedback systems: Stability, Nyquist-criteria, stability margins, sensitivity. Performance, transient and stationary properties, specification in both time and frequency domain.

Design of control systems: Basic principles for control design, possibilities and limitations. Design of PI- and PID controllers, cascade control and feed-forward. State space design.

Implementation: Implementation of a controller in a computer. Sampling and its consequences. Translation of continuous controllers to discrete controllers.

laboratory experiments: Control of water tanks.
Assignments: Assignments that are solved by mainly using Matlab.

Organisation

Teaching is in the form of lectures, group exercises and a two laboratory experiments that is solved in the department lab. There are also mandatory home assignments that are solved in groups of two.
