Combining Passion with Fundamentals - Applying Model-Based Design to Education

Model-Based Design is increasingly prevalent in industrial sectors including aerospace and automotive, but lacking from college and university curricula. The need for students to be adept at the modeling of systems, their associated subsystems, and overall system controller as per the standard industry practice is the impetus for The MathWorks, Freescale, and MotoTron to partner with Rose-Hulman Institute of Technology to address the lack of students familiar with this industry standard practice. Rose-Hulman Institute of Technology has created the Model-Based-System Design Center with the express purpose of introducing the philosophy of Model-Based Design to the educational community. This paper describes the function of the Center and the teaching materials currently being generated.

Engineering pulsed magnetic fields: Designing and building a pulsed magnetic field circuit for a faraday rotation experimental setup

Faraday rotation (FR) is a useful optical technique to investigate magnetic properties of solid and liquid samples. FR refers to magnetically induced birefringence whereby a substance rotates the polarization of a light beam passing through it, in the presence of a magnetic field. While FR experiments commonly employ either a DC or an AC magnetic field, obstacles exist for some samples with these setups. Overcoming some of these difficulties, a pulsed field setup has been designed and tested that allows for investigating magnetic response to short intense fields on the order of 1.5 Tesla and lasting 30 to 50 milliseconds.

Design of a plugin split-parallel Chevrolet Malibu: Control strategy development

As a selected participant in the EcoCAR2: Plugging In to the Future competition, headline sponsored by General Motors and the US Department of Energy, the Rose-Hulman team has completed the second year of a three year design cycle. This paper focuses on the supervisory control system design completed during year one of the competition including plant model development, control system hardware architecture, control system software architecture, vehicle operational modes, automated testing, and fault detection and mitigation.

Design and deployment of a mule plugin Split-Parallel Chevrolet Malibu: Integration

As a selected participant in the EcoCAR2: Plugging In to the Future competition, headline sponsored by General Motors and the US Department of Energy, the Rose-Hulman team has completed the second year of a three year design cycle. This paper focuses on the mechanical integration of powertrain components based on the year one design. The selected architecture, a plugin split-parallel, utilizes a GM LE9 2.4L Flexfuel engine, a GM MHH eAssist 6-speed automatic transmission, a modified GM BAS and inverter, a Remy HVH250 rear traction motor with Rinehart inverter, and custom A123 battery.
