pid control of single phase induction motor

Anyone could help me?...
How to control rotational speed, voltage, or power of single-phase induction motor ?
please replay this forum, and attach some schematics circuit for thats purpose...
thank you
 

You can use phase control methods, by using external interrupt pin to detect the zero crossing of AC source, then start to make the phase control signal at this point, also you can plus the PID controller to control it.
