Narrative:

Air carrier X departed anc filed V440 mcg at 100. The air carrier X was vectored north and south of V440 in an 'south' pattern to gain altitude due to an extremely slow rate of climb to 10;000. The air carrier X was 4.5 nm south of ivann in a 2;000 ft MVA at approximately 4;400 heading 320 and told to join V440. The pilot of the air carrier X informed me that he was unable to meet the crossing restriction at ivann of 5;000 ft. I acknowledged and then vectored the air carrier X away from ivann to the northeast and then back to a 230 heading to join V440 at ivann as the aircraft was approximately 5;100 ft and climbing. Pilot acknowledged. I then turned my attention to another aircraft and then I noticed the air carrier X approximately 3nm north of ivann not on V440 but on an approximate 270 degree heading entering the 5;900 ft MVA at 5;300 ft. I informed the air carrier X that he was not on V440 and north of ivann. The pilot acknowledged and I instructed him/her to join V440 from a 260 heading and resume own navigation. Pilot did not take vector to join airway at ivann. Slow climbing aircraft should file alternate route or be assigned a pdr route to keep the aircraft in lower MVA/MEA's. Controllers should not have to give excessive vectors and attention to aircraft because they can not perform normal rates of climb.
