dy_gains

 

Purpose:

Set dyno gains

Enter:

dy_gains <P> <I> <D>  [+s]  [m]  [+f] 

Where:

P Specify the desired Proportional gain for the dyno controller.
I Specify the desired Integral gain for the dyno controller.
D Specify the desired Derivative gain for the dyno controller.
+s Optional. Specify this flag to indicate the gains should be written to the ctrl_specs.NNN file.
m

Optional. Specify one of the following to indicate the target engine control mode. Gains are specific to each mode.
1 => DYNO_DYNO_TORQUE
2 => DYNO_NET_TORQUE
3 => DYNO_OTHER
4 => DYNO_SPEED
5 => DYNO_SPEED
6 => DYNO_SPEED

+f Optional. Specify this flag to indicate operator interaction is not required if the sign of the gains is not correct.

Example:

dy_gains   .05   .006   .01
The above command sets the gains of the dyno controller to:

Proportional gain = .05
Integral gain = .006
Derivative gain = .01

dy_gains   .05   .006   .01  +s    m=2  +f
NOTE: The first 3 values entered must always be the 3 gains. The other options follow.

The above command sets the gains of the dyno controller to:

Proportional gain = .05
Integral gain = .006
Derivative gain = .01

Also, the spec file is rewritten and the mode control value set to 1. No operator interaction is needed if the sign of the gains is not correct.
