Need help on speed control of single phase ac induction motor

I'm working on a project "single phase ac induction motor speed controller". The spec of the motor that im going to use is

230v,1/8hp ,8000rpm@no load

I want to know whether it is possible to control the motor for speed upto 5000 and in steps of 100 from 0 without having the problem of overshoot and delay to achieve max speed

my control options are only phase angle control using triac or slip control using IGBT.

which is the best suitable option out of this ?

Any help would be appreciated

Thanks in advance
