Narrative:

During radar vectors to final approach ILS 17L mco base leg encountered severe wake turbulence. Aircraft on a 90 degree base leg; assigned speed 210 KIAS; descending 4000 to 3000 ft; aircraft suddenly rocked side to side disengaging autopilot. I immediately determined we were going to overshoot localizer because [of the] angle to localizer. I am hand flying at this point trying to get aircraft back on localizer and not bust altitude. Controller noticed our difficulty and asked if we would want to do a 360 and try again. I told first officer (first officer) to report the wake turbulence to controller which he did. No traffic in our vicinity at the time of occurrence.too close to traffic ahead of us on same flight path. ATC should not be assigning a speed of 210 KIAS on a 90 degree angle to localizer when less than 2 miles from intercept.
