Abstract: In this paper,a highreliability and energy-saving type of automatic deicing system for aireraft is proposed.In this system,the electric separation deicing method and the optimal energy control strategy are used,in order to save deicing energy consumed by the automatic deicing system. In this system,the faulttolerance system structure is adopted to improve the reliabilitv of the automatic deicing system. The test resuIts show that this automatic deicing sys tem is a high reliability system,and the effect of energy,saving is remarkable.

Key words: deicers, automatic control, fault tolerance
