Signal and Automatic

  • Voir la page en français

    In brief

  • Code : N6EM02A


The objective is to acquire tools of the engineer in deterministic signal processing and automatic continuous time, for a first approach of the main aspects related to the mechanical vibrations in an industrial context: the modeling, the measurement, the control. Localized parameter modeling (lumped parameters) is preferred.


The module consists of two parts:

I Modal Experimental Analysis (4 CM, 6TD, 1TP):    


- SLI Model Linear Invariant System   

-  Introduction to the concepts of organization and interaction. 

- Frequency Response Function (F.R.F).     

- Oscillatory and aperiodic mode. Stability.     

- Convolution property. Memory effect.     

- Filtering (RII, RIF).   

- Introduction to the signal concept (Fourier analysis)     

- Digital identification techniques     

- Consequences of temporal truncation (spectral leakage, resolution)

- Time Sampling Effects (Spectral Folding, Shannon's Th.)     

- Discrete TF (reciprocal Shannon th)  

- TP Modal Experimental Analysis: Modal identification (impact hammer) and detection of defects of a rotating machine (real-time monitoring by Simulink RTW, problem of starting and stopping machine). Resonance and anti-resonance of a 2 ddl system.  


II APP Vibrations Under Control (project by team)  


- Through Project Based Learning, students acquire basic concepts and knowledge to control a hydromechanical process. The teaching team (5 tutors, one expert) has defined the following learning objectives:    

- The concept of system to represent a physical process.   

- Knowing how to translate the organization (the natural or artificial interactions) of a system by a recursive functional diagram (looped).  

- To be able to translate the phenomena of his specialty, by associations of elementary models: Inertial effect, Resistive, Capacitive.  

- Identify a basic hydromechanical process by analyzing the response to a deterministic solicitation (behavior model)   

- Linearize a nonlinear model around an operating point to obtain a model L.T.I. (Linear Invariant System) in transfer.     

- Determine the stability of a system controlled by the Nyquist criterion. 

- Understand the risks of looped architecture (influence of phase delays on stability). 

- Understand the interest of the looped architecture for performance (for stability, to manage disturbances). 

- Know how to adapt a Proportional controller taking into account the antagonisms between performances (stability / precision, speed / sensitivity to noise). An "agile coach" accompanies teams for project management (SCRUM method).
