【Abstract】 This paper presents a kind of new design way of electromechanical system of high performance linear servo motor that is of digital feedback,including the hardware and control system design. This system adopts grating to measure the position and uses the DSP to process the signal, and applies the control algorithm based on a non-linear state observer,then the electromechanical dynamic performance of system has been improved greatly. The control error has been reduced greatly and the track performance has been improved greatly.更多还原
