From the Angle of the theory, study for a practical system model parameter identification problem. First, a mathematic model of the missile servo control system is set up . Experiment is done under no-load frequency sweep, the control system is often a third order linear system. Then on this basis, the research of the model parameters to be identified and system parameter identification method of the model. Using the actual data collected, through the recursive least squares algorithm for missile identification was carried out on the parameters of the mathematical model of servo control system, get the model parameters under normal work.Finally, the paper puts forward the full text; and the next step focus and direction are also discussed.Key Word: System identification;The third order linear system;Recursive least squares algorithm目 录1 绪论11.1 系统辨识的定义11.2 课题来源及讨论的目的和意义11.2.1 课题来...
