The national defence basic project as background and the dynamic model of cotrolled transfer matrix for multiple launch rocket was created in order to reduce the initial disturbance of rocket projectile. The causes that affect the angle change of orientation locator were analyzed by the engineering system dynamic theory base on multibody system transfer matrix method. The simulation of dispersion for multiple launch rocket was implementation, and the affect law between the angle of elevation and side deflection and the control parameters was acquired. The control module was installed on the orientation locator of multiple rocket launcher to control the initial disturbance of rocket that provide new method and theory base and show the engineering system dynamic base on the multibody system transfer matrix method is effective.
