The Research Of Motion Control System Based On DSP

It's based on the combination of software and hardware that motion control realizes the good precision of position control and speed control in machine motion. Position control is one of the motion control,it requires high control precision and high trace speed,so how to improve the dynamic characteristic and how to reduce the contour error of the system are the keys of the control.In this thesis,we achieve a test-bed of motion control based on DSP using TMS320F240 EVM,XDS510 emulator,PC,AC servo driver,AC permanent magnet synchronic servo motor and two direction graph plotter etc. The thesis analyzes the influence that the dynamic characteristic and the change of parameter of the system cause contour error of the system,then adopts Fuzzy adaptive PID control method,single neural cell PID control method and Fuzzy-neural network control method,and introduces the influence that the control methods lead to dynamic characteristic and contour error of the system. Finally some useful results are obtained by analyzing and comparing the control methods,and it is possible to make the combination of advanced control methods and high efficiency of DSP.
