Matlab Feeback Framework

• allows user to defined Actuators, States and
  Measurements as PV lists
• allows the user to save/restore configuration
  values (limits on actuator, state and measurement
  values PID values, timer intervals etc) on a
  softIOC
• allows the user to start/stop feedback and change
  state setpoints dynamically
• performs the actual feedback calculations

5
Feedback Support soft IOC

• stores the last 1000 points of actuator, state,
  and measurement values
• stores configuration parameters
• edm screens allows user to view the current
  feedback performance in real-time

6
Feedback Simulator soft IOC

• simulates Measurement (BPM, BLEN, energy,
  current) values based  on changes in RF or Magnet
  values

Individual Feedback Status

• DL1 Energy - PID feedback coded and tested with
  simulator
• Spect. Dump Energy - PID feedback coded and
  tested with simulator
• DL1 Energy BC1 energy Bunch Length - PID
  feedback coded and tested with simulator
• Injector Launch feedback - algorithm needs work
• Bunch Charge Feedback - need algorithm definition

Matlab Feedback Concerns

• memory issues - need to test on systems in MCC
• how will it perform over several hours?
• can we run more than one feedback per kiosk or
  desktop in MCC?

Whats not done?

• No background images available because MPS Burst
  Mode hasnt been implemented. Physicists are
  asking for an alternate, maybe temporary, method
  to collect background images.
• TCAV hasnt been commissioned.
• Channel Access can be slow to Profile Monitor
  IOCs.
