1. A hybrid deicing system, comprising:
a first deicing system coupled to a high critical zone of a control surface, the first deicing system providing thermal energy to the high critical zone of the control surface to remove ice from the control surface;
a second deicing system coupled to a low critical zone of the control surface, the second deicing system configured to vibrate the control surface to remove ice from the control surface;
a controller configured to control the first deicing system and the second deicing system;
a heater power control configured to provide heat to the first deicing system; and
a zonal piezo control configured to provide an input frequency to the second deicing system.
