• An inclusive and benevolent environment
• Recognized societal and environmental commitment (Thales Solidarity, CAC 40 ESG index…)

Your daily life

At the heart of Saint Quentin en Yvelines, the Elancourt site is one of Thales' most important technological centers of excellence. The diversity and technicality of the systems and equipment mobilize expertise in more than 80 professions in defense, high-tech security, and digital services solutions.

The Servomechanisms & Servo Control Service (SSA) brings together the skills and resources necessary for the development of functionalities related to servo control for all of Elancourt's product lines: servo-controlled mechanisms, line-of-sight stabilization and kinematics, line-of-sight attitude calculations, and georeferencing. As such, SSA intervenes throughout the product life cycle: from architecture and sizing, through development and integration, to expertise in production and operational maintenance.

The internship is part of the study and development work on the line-of-sight servo control of an airborne optronic system. This servo control must meet a need for high precision, while being constrained by an environment presenting strong frequency disturbances and the presence of delays in the loop (command and measurement chain).

The objective is the development (in simulation) of algorithms (simple and efficient) for compensating disturbing torques while considering the effect of delay.

A first development has been done on 3 types of compensators. During the internship, you will take over the work done to add layers of in-depth analysis.

More precisely, you will be led to work on the following missions:

• Taking ownership of the model

Understand the dynamics and effects of disturbances and delay.

• Closed-loop analysis without compensator

Analyze sensitivity functions and stability margins.

• Implementation of a first modified Smith predictor type compensator

Closed-loop analysis, and robustness margins.

• Proposal of other compensators (state observer type, MRAC, or H-infinity):

Closed-loop analysis, and robustness margins.

• Comparison of the effect of each compensator on sensitivity functions, robustness margins, and setpoint tracking.
• Justify the interest of each compensator on the type of system (dynamics) considered, according to the frequency distribution of disturbances in a general and modular case.

Your profile

Are you looking for your end-of-study internship at bac+5 level in systems control, servo control?

Do you have solid theoretical knowledge in linear and non-linear automation (servo control)?

Do you therefore have a first experience (internship or project) in implementing PID control on a mechatronic system?

Do you master Matlab/Simulink?

Do you demonstrate a certain aptitude for analytical development, simulation, and analysis?

Are you recognized for your rigor, your synthesis capacity, your proactivity, and your perseverance?

Then this internship is for you!

A word from the team

This internship offers the intern an opportunity to deepen their knowledge in automation and servo control, but also to be a source of innovative proposals. The results will potentially be exploited during the development of Thales products. You will join a young, welcoming, and cheerful team, who will support you in your success!

All our internships are conventional and subject to a gratification whose amount is determined according to your level of study.

Thales, a Handi-Engaged company, recognizes all talents. Diversity is our best asset. Apply and join us!
