Servo System Modeling And Verification

Servo-System as well as the name of follow moving system,is one kind of the automata.The function of it is to control the corner or displacement of the undercontrol object to move with the instruction,and the moving is automatically ,continuously and accurately.The right mathematic model is important to the design of the Servo-System ,And the dynamic mathematic model that can fully describe the dynamic characteristic of the system is much more.It is crucial to the final performance of the system.Only the model is fine, can the static and dynamic characteristic and the precision of the system behave well.This paper simplely expatiate the developing history of the system modeling and emulation.give a describe of the basic way of modeling and emulation of the Servo-System.And it give a material tell of how to design the current ring,velocity ring ,and the position ring of the digital Servo-System,so we can know the whole process of designing the digital Servo-System of radar.Incorporate with MATLAB/Simulink's technology predominance at systems analysis,analyse actuality and trend of development of system modeling and emulation, give the technical line and realize frame of subject study. At the same time,compute the position ring, velocity ring, current ring,erect relevant mathematical model,set and distinguish the electric parameter and mechanism parameter,erect the individual transfer function,thus in turn deduce the transfer function of the whole system.Analyse the system response, system stability, timedomain with MATLAB,at last test the accuracy of the model in the project of our factory.The paper give a modeling and emulation of the Servo-System ,when doing this ,we can amend the parameter to fit the real system.so it has some value to the theory and engineering.
