My active comnaded airspeed is aways 25 (show in energy-control settings tab).
ever i change this value to 15 or 30 the plane ever fly at 18~20m/s.
i saw that all other values @ energy-control settings tab are 0 .
i will try to change p to airspeed today.

The defines you put here are only referred to by the versatile_airspeed.xml flightplan so far: [https://github.com/paparazzi/paparazzi/blob/v4.1/conf/flight_plans/versatile_airspeed.xml]
In any case in the energy-control settings tab, the current airspeed setting is shown. So if you flightplan does not overrule it you can also set it by hand there. What was your ACTIVE commanded airspeed?
At present, the energy-control file still has too many gains, allowing you to also configure the controller as non-airspeed, throttle-from-airspeed, pitch-from-airspeed, and finally the last 4 gains: energy-control. If any of the integrators are non-zero, the plane will compensate UNTIL the goal is reached, (whatever that means so be careful here).
Please note there are also outerloop gains: alt_pgain (e.g. 0.1 means 10 meters low = 1m/s climb) and speed_pgain (e.g. 0.3 means 1m/s too slow = 0.3g = 3m/s2 forward acceleration). If this gain is zero, the airspeed will indeed not be controlled.
Also note that energy-control expects an IMU.
PS: please understand this is still in the experimental phase: so your feedback/results are very welcome.
