gain scheduling

[Dr Jon Atkinson]

Hi

When you use the Gain Scheduling VI, in the PID Toolkit, what happens if you
only define one set of PID parameters? e.g. my parameters are set to work up
until the setpoint is 100, but I have not set any further parameters above
100. Does the algorithm continue to use the same parameters once the
setpoint has gone above 100?


Thanks

Jon

Jon,

If your scheduling input (setpoint in your case) is larger than your last gain schedule value, then the gains for the last gain schedule element will be selected. So if your setpoint goes above 100, the parameters for 100 are still used. Get PID parameters

Note: When adding elements to your gain schedule, make sure your gain schedule array is ordered from lowest to highest.
