Abstract: A kind of new design way of electromechanical system of the high performance linear servo motor, including the hardware and control system is presented. Because this system adopt raster to measure the position and uses the DSP to process the signal, and apply the sliding mode control arithmetic based on the state observer, the electromechanical dynamic performance of linear servo motor is tested in experimental environment, the result shows that the performance of this system is very high.
