Abstract: By establishing impulse force based trajectory model, uniform design method was used to convert the problem of determining control parameters of the actuator into the design of experiment with multi-factor and multi-level. A new uniform design table was worked out to arrange simulation test. The relationship model among impulse ignition time, impulse working numbers and total value of trajectory correction was obtained by using regression analysis. On the basis of the model and the calculation formula of impulse ignition phase, a control method of projectile-borne actuator was proposed. Example simulation has testified the validity of this method.
