ES4F0-15 Advanced Control Systems
Introductory description
ES4F0-15 Advanced Control Systems
Module aims
The aims of the module are to build on the knowledge of control systems that students have acquired in previous years and teach them the advanced techniques for the design and analysis of real-world control systems that are currently used in multiple engineering industries (e.g. aerospace, automotive, robotics, power systems, electronic systems, etc).
We will do this by:
- Focusing on advanced design and analysis techniques currently used in industry, rather than on outdated or unapplicable theory.
- Focusing on learning how to use powerful software tools (e.g. the Matlab Robust Control Toolbox) to design and analyse control systems for realistic applications, rather than on pencil-and-paper type solutions to simplified mathematical problems.
- Embedding consideration of real-world constraints (uncertainty, disturbances, actuator saturation, etc) into all design and analysis frameworks.
- Teaching theory via detailed examples from a variety of application domains, with Matlab code included throughout.
- Assessing student's learning via software-based marked assignments, e.g. the complete design and analysis of a controller for a challenging real-world problem, rather than via pencil-and-paper exam questions.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
- Introduction to uncertainty and robustness
- Useful tools from linear systems theory (signal and system norms, stability, performance measures, etc)
- Unstructured uncertainty and generalized stability margins
- H-infinity mixed sensitivity design - single-input-single-output systems
- H-infinity loopshaping design - single-input-single-output systems
- Useful tools from linear systems theory (small gain theorem, singular value decomposition, multivariable Nyquist criterion, etc)
- H-infinity mixed sensitivity design - multi-input-multi-output systems
- H-infinity loopshaping design - multi-input-multi-output systems
- Structured uncertainty and mu-analysis
- Actuator saturation and anti-windup
- Gain scheduling
Learning outcomes
By the end of the module, students should be able to:
- Model the effects of different forms of uncertainty in control systems, and analyse the robustness of closed-loop systems to unstructured uncertainty
- Design robust multivariable controllers using advanced synthesis methods (H-infinity Loopshaping etc) for challenging application problems
- Analyse the robustness of multivariable controllers to structured uncertainty using advanced methods such as mu-analysis
- Understand how to deal with different sources of nonlinearity (actuator saturation, nonlinear process dynamics) within a linear design and analysis framework using techniques such as anti-windup and gain-scheduling.
- Use advanced control system design and analysis environments and Matlab toolboxes.
