It is an important problem how to effectively transform the information of time and attitude into aircraft's expectation control command of velocity and attitude on condition of taking UCAV's performance constrains into account. This paper presents a new method which apply maneuver movement matching planned path by establishing maneuver action database to create the expectation commands such as thrust brake gate, perpendicular load, flight path angle and flight path bank. The UCAV's performance constrains are taken into consideration in the design of the method, so the created expectation commands are reasonable and easy to be realized. The results of simulation show that the method has a good real-time and the created command is easy to be followed.
