Gain Setup
- Gain setup offers parameters that adjust the
steering in unique circumstances. There are three adjustments
you may make for Gain:
•
Integral Gain
: 0.0 to 100.0 with 0.0 as the default. Increase
this value to get less steady-state error, but also less
stability. Steady-state error is error caused by non-
linearity in the valve. If more effort is required to move
the valve in one direction than another, such as near full-
open versus full-closed or left versus right, then add 0.5
to 1.0 to the integral gain value. If the valve operation is
mostly linear, then leave the integral gain at 0.0.
•
Derivative Gain
: 0.0 to 100.0 with 0.0 as the default.
Increase this value to get less overshoot (more stability),
but less responsiveness. Generally, this value is left at 0.
•
Dead Band
: 0.0 to 1.0 with the default at 0.1. This is the
amount of acceptable error in turning rate (i.e., the
steering will not respond if the desired turn rate is within
0.1 deg/sec of the actual turn rate). As you increase this
value you get more stability, but also more steady-state
error. This may need to be increased on articulated
vehicles, but 0.1 is typically ideal for wheeled vehicles.
