Figure 13 shows the picture of the experiment equipment and the software runtime is shown in figure 14. Fig. 12. Structure of the Position Control System Fig. 13. Picture of the Control System Fig. 14. Picture of the running WinCon System model and position controller design Traditional control method and controller design is commonly based on mathematics model of the object under control and the controller is calculated according to required performance. Generally mathematics model of the system is obtained by the method of analyze or system Mass Inertia Effect based Vibration Control Systems for Civil Engineering Structure and Infrastructure 115 identify estimating model from the input and output experimental data. For the mathematic expression of asynchronous linear motor is so complex and parameters the manufacturer offered is not enough to build the model from analyze. At the same time experiment situation of linear motor is limited by dimensions of the platform so experiments can t be implemented to get enough data system identify required which makes design of the controller much more difficult. In the engineering problem design process simplification of the mathematics model usually makes the controller difficult to actualize or get awful performance. So a simple and facile approach that fits the engineering application is necessary. This part analyzes and summarizes most of the design methods and tries a new design method. Reference to the design method of Extraction of Features of Object s Response briefly EFOR an approach to design the Lag-Lead compensator based on the experimental step response of the closed-loop system is implemented and good performances is achieved. Basic idea of quondam EFOR method is described as below closed-loop simulation is carried out to a series of Normal Object to get the step response and then some main time characteristic parameters are .
