Narrative:
Approaching runway 18R on the localizer near glide slope intercept encountered significant wake turbulence. ATC stated preceding aircraft was a B757 4 miles ahead. Aircraft was temporarily uncontrollable. Autopilot was disconnected and aircraft slowed to minimum approach speed while maintaining flight path above the glide slope.ATC has decided that the previous 5 mile spacing behind B757 aircraft is no longer required when in fact we were vectored too close behind the preceding aircraft to conduct safe operations. Provide the previously required 5 mile spacing behind B757 aircraft.
