Application Notes

• Particle accelerator used for cancer therapy without damaging healthy tissue

• Wide energy range from 60 MeV to 800 MeV per nucleon with selectable beam energy in steps of 0.1 MeV

• 300,000 settings for the beam based on particle type, ion source, beam line, energy level, beam dimension, and spill length

• Concurrent beam control and reconfiguration in less than 250 msec

• Reconfigure the software on the FPGA for the next cycle while current beam is generated

• Distributed control system synchronously generates magnetic fields for 300 magnets by generating waveforms for power converters in real time at 2 kHz

• Power converter synchronization at the microsecond level to generate/control the beam

• Power converters distributed over 800 m2 in access controlled area

• 500 beam cycles with different beam energies for a single medical irradiation session of about 2 minutes duration

• More than 20,000 shared variables for control, configuration, and monitoring

• Solution completed in time because the researchers did not need to learn VHDL

Title Controlling a Hydraulic Motion Compensated Gangway to Access Offshore Wind Turbines

Author Andrew Clegg - Industrial Systems & Control LTD, UK

Challenge

Creating a system to safely transfer personnel & equipment to offshore wind turbines in rolling seas & bad weather

Solution Using LabVIEW & cRIO to develop a movable gangway with an algorithm using boat motions to provide required hydraulic cylinder lengths to maintain position

wind turbines located further offshore, sea conditions become adverse

transferring personnel to sea based wind turbines for maintenance

moveable gangway mounted on hydraulically actuated base on boat front

up & down pitch cylinder, forward & back surge cylinder, port/starboard roll cylinder

compensate for boat motions in roll, pitch, heave

Used LVRT, FPGA & MathScript RT modules

did dynamic simulations to test control strat & hydraulic specs to meet perf targets

sw emulator to test algorithm functionality

switched to real system to explore control loop performance for different loads, size, speed of motions, orientations

I/O & control algorithm on cRIO

Motion Reference Unit measures vessel motion, transmits positions & angles via serial link to MPU

use mathscript nodes in LV for complex algorithms

Inverse kinematics transforms motion plan into joint actuator trajectories

calculate cylinder lengths & maintain gangway tip fixed in space

real time cascade control with feedforward & nonlinear compensation

cylinder length error for simulation & real testing showed simulation was reasonable rep of final system

development, implementation & factory testing took a little more than a year

sea trials confirm that range of motion compensation meets expectations from final factory testing
