Open CNC systems and high-performance motion controller has become the direction of development of the numerical control technology . The motion controller has been out of the machining industry , more and more used in other industrial automation equipment control . In this paper, based on TI's 16-bit fixed-point DSP chip TMS320LF2407A motion controller for the study, a brief introduction to the composition of its hardware , and elaborate the design of the control system of the motion controller . The main research contents are as follows : By analyzing the status quo of the development of the motion control technology at home and abroad , combined with the latest research results in the open CNC system developed multi-axis motion controller based on DSP control system , real - time multi-tasking operating system, μC / OS-Ⅱ the TMS320LF2407A transplant , using state-of-the-art interpolation algorithm with the position control algorithm . The motion controller hardware design , the design of the system power supply , clock , reset , JTAG emulation interface , LCD driver , keyboard input , memory expansion , DAC expansion circuit . Build a PC-DSP USB communication circuit . Realization of real-time embedded systems μC/OS- Ⅱ transplanted into the controller , and the optimization method to improve the reliability and stability of the system . In the control algorithm , a detailed analysis of the characteristics of the location of the conventional PID control algorithm , using a simple , fast convergence , single neuron adaptive PID control algorithm . Motion control system , the superiority of cubic B-spline constant speed interpolation algorithm based on cubic B-spline curve time constant speed interpolation algorithm , based on the cubic B-spline algorithm , elaborated VC algorithm simulation.
