Goals for the FLOAT Team

Ultimate Goal of Research A successful test will provide motivation for increased

research into FMCs KC-135 Test Objective

To design a control system that, after an initial disturbance, will be able to return the apparatus to its original position within 20 seconds

Fluid Loops and Pumps Accelerate Fluid to

generate a change in angular momentum

Apply torques over time to negate disturbance effects

Accelerometers Read acceleration

rates of 6 faces Input voltages to

control system corresponding to accelerations

FieldPoint Stand-alone control

system Integrated modular

input/output distributor 3 modules

Control module Input module Output module

Batteries Supply power to

control module Control module

distributes and regulates power
