The invention discloses a butterfly-shaped flight vehicle attitude angle steady-tracking method based on a terminal-type fuzzy slide model. A pitch attitude angle and angular speed of a butterfly-shaped flight vehicle are measured and are fed back and compared with an expected pitch angle signal to obtain an error signal, then a terminal-type sliding mode surface is constructed through the error signal and an attitude angle speed signal, and the equivalent control amount and the control amount of the fuzzy slide model are respectively designed according to the error signal and the sliding mode surface. A fuzzy system is established, a fuzzy rule base and a rule matrix are established based on the principle that an error is greater, the bigger the control amount is and the bigger control gain is, a defuzzification method is adopted to calculate sliding-mode control gain, the sliding-mode control amount is compounded with equivalent control after being substituted to form a final total control amount, and finally a simultaneous saturation reaching method is adopted to perform control law distribution of air injection and mass moment control. Rapid tracking of given attitude angle signals is achieved, and the flight control stability of a butterfly-shaped flight vehicle pitching channel is ensured.
