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
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.
