Objectives
General knowledge of control, including most common techniques and methods in MIMO control (multivariable) and state-space approaches; analysis and design skills through practical applications of the different techniques such as state estimate using Kalman Filter; design optimal and adaptive systems
Program
1 - Introduction and Reviews: Controllability and observability; design of state feedback and output feedback control: Ackermann's formula.
2 - Regulator Design and Reference Following: Controller with state observer; Predictor estimator; Current estimator. Reference inputs for full-state feedback systems; reference input with estimators; reference input with output error command; comparison of the estimator structure and classical methods.
3 - Disturbances and Control by State Augmentation: Disturbances estimation; Control by state augmentation, including the process model; Control by state augmentation, including the disturbances model; Integral control action.
4 - Adaptive Control: Least Squares Method; parameter estimate.
5 - MIMO Systems and Optimal Control: Time-varying optimal control; Linear quadratic regulator (LQR) steady-state optimal control; Optimal estimation based on Kalman Filter; Multivariable Control Design.
6 - Brief introduction to system identification techniques.
Evaluation Methodology
Exam (50%) and practical assignments (50%). The student must obtain a minimum grade of 8 marks (on a scale of 0 to 20) in the exam and a minimum grade of 9.5 marks (on a scale of 0 to 20) in the practical assignments. The average of the two components must be greater than or equal to 9.5 marks (on a scale of 0 to 20).
