Robotics, Control and Systems
2nd Cycle Studies - Mestrado
Signals and Systems; Signal Processing; Control, Physics (Mechanics)
Lectures involving detailed presentation of concepts, principles and theories that constitute the materials of the curricular unit and solving exercises with active participation of students.
Laboratory classes where students perform simulation studies in Matlab/Simulink. Additionally, students have access to a wide range of theoretical and practical problems solved and others for resolution.
The adopted evaluation aims to stimulate a process of continuous study and learning, considering two components of assessment: theoretical/practical and laboratory.
Objectives: Provide students with the main concepts, principles and theories that enable the analysis and design of computer-controlled systems that include both continuous systems and components of information processing in discrete time (discrete-time controllers with and without state observers)
Skills to develop: It is intended that students acquire skills in analysis and synthesis, formulation and problem solving, critical thinking, independent learning and ability to apply theoretical concepts in solving practical problems.
