Safety of gyroplane is so widely accepted that a study of the stability and control characteristics is necessary. Based on the dynamic model, sliding mode control method is adopted to ensure its longitudinal stability. However, for traditional sliding mode control, the switching control term brings the chattering problem. So a fuzzy sliding mode control system, based on Mamdani fuzzy switching strategy, is designed to improve the longitudinal dynamic stability characteristics. Simulation demonstrated that the proposed control method has an excellent dynamic performance and the chattering phenomena can be attenuated effectively.
