Prerequisites
Basic undergraduate background in mathematics and notions of signals and systems (e.g., as taught in LEPL1106).
Main themes
This course provides a comprehensive introduction to the modeling, analysis, and design of linear control systems. It begins by presenting techniques for modeling physical systems using differential equations and transfer functions, with examples drawn from robotics, mechanical, electrical, biological, and biomedical engineering. The course then explores methods for analyzing these models, focusing on key system properties such as stability, steady-state errors, disturbance rejection, and the role of feedback in ensuring robustness.
One part of the course is devoted to classical control design techniques using frequency-domain tools — such as PID tuning and frequency-domain methods — as well as robustness analysis. Another part focuses on system analysis and control synthesis using state-space methods, offering a modern framework that supports the study and design of controllers via state feedback. Particular emphasis is placed on the use of software tools for controller design
Learning outcomes

At the end of this learning unit, the student is able to :

  • Model physical systems using both transfer function and state-space representations, with applications to mechanical, electrical, and process control systems.
  • Analyze system properties such as stability, transient response, steady-state error, and robustness using time-domain and frequency-domain techniques.
  • Translate design specifications into control specifications
  • Apply classical control design techniques, such as PID control, root locus, Bode plots, and Nyquist criterion, to meet specifications.
  • Design and analyze feedback control systems to ensure performance and robustness against disturbances, noise, and model uncertainties.
  • Develop and use state-space models for the analysis of dynamic systems, including the assessment of controllability, observability, and internal stability.
  • Synthesize state-feedback controllers and observers using, for example, pole placement and Linear Quadratic Regulator (LQR) methods.
  • Translate control design problems into practical implementations using software tools (for example, MATLAB and Simulink, leveraging the Control System Toolbox).
  • Solve practical control problems in lab settings, including fluid tank regulation, distillation process control, and robot control.
  • Autonomously run automatic control experiments, from the design level to the actual implementation and performance evaluations.
  • Communicate technical findings concisely through written reports and work in a team to develop control strategies in group settings.
  • Demonstrate the ability to independently apply learned concepts to solve unseen control problems under time constraints.
 
Content
The course is organized in two main parts:
 
Part 1 - Analysis of systems using frequency-domain tools: Laplace transforms, dynamic response, transfer functions, system poles, block diagrams, stability, PID control, Bode and Nyquist diagrams, lead and lag compensators.

Part 2 - Analysis of systems using time-domain tools: state-space models, matrix exponentials, linearization, linear time-varying systems, Lyapunov stability, controllability and observability, pole placement, advanced control via state feedback.
Teaching methods
Learning will be based on lectures (in presence mode or in distance mode) interlaced with exercise sessions (offered in class with the support of TAs) and laboratory sessions (to be realized in the laboratory room by groups of 2-5 students using laboratory equipment and MATLAB Simulink).
Evaluation methods
  • Written exam
  • Laboratory evaluations taking place during the semester
  • Quiz exercises taking place during the semester
  • Other activities, such as homework or oral evaluations, may used to compose the final grade
  • The laboratory grade cannot be carried over from previous years. The laboratory experiences cannot be accomplished outside the semester.
The final grade is weighted as follows: 60% for the written exam, 20% for laboratory assessments, and 20% for assessments during the semester.
Other information
The main language used during lectures, exercise sessions, and the laboratory is English. Examinations can be made French-friendly, upon request.
