Purpose:<\/h3>\n<\/div>\n
\n
\n

Set the proportional, integral, and derivative gains for the throttle controller.<\/p>\n<\/dd>\n<\/dl>\n

Enter:<\/h3>\n
\n
\n

th_gains<\/strong> <proportional_gain> <integral_gain> <derivative_gain> [+s] [m=control_mode]<\/p>\n<\/dd>\n<\/dl>\n

Where:<\/h3>\n
\n
\n\n\n\n<\/colgroup>\n\n\n\n\n\n\n
\n

proportional_gain<\/p>\n<\/td>\n

\n

Specify the desired Proportional gain value for the throttle controller.<\/p>\n<\/td>\n<\/tr>\n

\n

integral_gain<\/p>\n<\/td>\n

\n

Specify the desired Integral gain value for the throttle controller.<\/p>\n<\/td>\n<\/tr>\n

\n

derivative_gain<\/p>\n<\/td>\n

\n

Specify the desired Derivative gain value for the throttle controller.<\/p>\n<\/td>\n<\/tr>\n

\n

+s<\/p>\n<\/td>\n

\n

Optional. Specify this flag to\u00a0indicate the gains should be written to the ctrl_specs.NNN file.<\/p>\n<\/td>\n<\/tr>\n

\n

m=control_mode<\/p>\n<\/td>\n

\n

Optional.\u00a0Specify the target engine control mode (as gains are specific to each mode):
\n1 => THROT_SPEED
\n2 => THROT_SPEED
\n3 => THROT_SPEED
\n4 => THROT_GROSS_TORQUE
\n5 => THROT_NET_TORQUE
\n6 => THROT_OTHER<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/dd>\n<\/dl>\n

Example:<\/h3>\n
\n
\n

th_gains<\/strong> .08 .003 .02<\/p>\n

The above command sets the gains of the throttle controller to:
\nProportional gain = .08
\nIntegral gain = .003
\nDerivative gain = .02<\/p>\n<\/dd>\n<\/dl>\n

Notes:<\/h3>\n
\n
\n

The program checks that all gains have the same sign and prompts for confirmation. If not, ensure values are appropriate for the current control mode.<\/p>\n<\/dd>\n<\/dl>\n
