With more than 8,000 employees, John Cockerill achieved a turnover of € 1.417 billion in 2024 in 28 countries, on 5 continents.
John Cockerill has been providing its expertise to the defense industry for 200 years. Today, John Cockerill Defense offers Cockerill® modular gun turrets from 25 to 120 mm caliber, Arquus® high-mobility vehicles, technical and tactical training on these systems, and Agueris simulators.
Your Mission:
The goal of this thesis is to develop custom compact, robust and fast acquisition system for interfacing a resolver sensor.
A resolver is an analog sensor that provides precise angular position feedback, crucial for controlling the orientation of the turret. The project involves understanding resolver principles, designing signal conditioning and acquisition circuits and implementing data acquisition in the processing system.
The system should also be able to process at high refresh rate the data captured for control and safety purposes and it should be able to provide different type of interfaces for external data transmission.
1. Exploration and need definition
You will study the resolvers and their applications and draft a specification document defining the scope of the study. In this specification, the performance criteria, the functional requirements (interfaces with controller) and the environmental constrains will be defined.
2. Architecture
An architecture should be defined to describe the different blocs that constitutes the design.
3. Design and prototyping
You will design the defined solution by developing a PCB that can be integrated in an existing IOBrick platform.
You will also interface the signal in an MPSoC platform, communicating through an FPGA and making the digital values of the resolver available in the processing unit.
4. Create one prototype.
The PCB will be assembled and tested in the complete subsystem. The PCB will be tested functionally to compare the developed solution regarding the initial specifications.
