Abstract In this chapter, a brief background about mechatronics systems has been presented by starting with the definition and key elements of mechatronics systems, providing some examples about it, introducing the improved and new functions gained using mechatronics system, giving some explanation about the integration of components (Hardware) and through the integration of information processing (software), providing a comparison between the mechatronics systems and conventional electro-mechanical systems, introducing to mechatronics systems control and some previous work is presented, and finally, one of the most popular mechatronics systems, X-Y table in CNC milling machines, is presented in details by providing the model of the DC motor which is used in the driving of each axis of the X-Y table. Some nonlinearities that may occurs in DC motors have been presented in this chapter. In the next chapter, the iterative learning control (ILC) will be presented and it will be applied to two DC motors used for X-axis and Y-axis. |
