Description

1. General:
   • Concept of continuous system
   • Definition and properties (necessary for the rest) of the Laplace Transformation.
   • Application to electrical networks.
   • Continuous transfer functions
   • Temporal responses by the TL (transient and permanent regimes)
   • Harmonic analyses. Representations of Bode and Black (Nyquist).
2. Definition and analysis of looped systems:
   • Open loop, closed loop.
   • Analysis of systems controlled by their transfer locations and by the placement of their poles (equivalent damping, resonance, static gain, etc.).
   • Stability and robustness of linear servo systems (geometric criterion based on Bode and Black-Nichols)
   • Accuracy of linear servo systems.
   • Correctors (PI, phase advance, etc.)

Learning Outcomes AAv (AAv)

• AAv1 [heures: 15, A1, B1, C1] : At the end of the semester, students will be able to model in the form of an exploitable transfer function a linear and time-invariant system (SLIT) with one input and an output (SISO) described by a system of mechanical and/or electrical equations, and to criticize the domain of validity of this modeling.

• AAv2 [heures: 15, B2, B3, B4] : At the end of the semester, students will be able to use mathematical tools such as the Laplace transform to characterize temporal behavior (static deviation, overshoot, response time) d a closed-loop SLIT system.

• AAv3 [heures: 10, B4, C1, C3] : At the end of the semester, students will be able to exploit different representations to predict the behavior of a closed-loop SLIT system. These representations include Bode, Nyquist and Black diagrams.

• AAv4 [heures: 10, B4, C3] : At the end of the semester, students will be able to criticize the performance of a correction strategy based on the closed-loop index response using criteria such as precision, dynamic performance and robustness.

• AAv5 [heures: 15, A1, A3, B4] : At the end of the semester, students will be able to synthesize using a frequency method (Black Nichols) an analog corrector of type P, PI, PID, to control a SLIT system in respecting the constraints of a specification. Students will be able to validate the performance of their corrector with simulation software.

• AAv6 [heures: 25, D3, D4] : At the end of the semester, students will be able to master measurement and testing methods using an oscilloscope, and will be able to design a linear corrector of type P, PI or PID to control a physical SISO system. They will also be able to check the performance of the corrector.
