摘　　要：提出了一种基于"PC+DSP运动控制器"的上位机+下位机的嵌入式运动数控系统,针对在连续控制过程中传统PID控制方法已经不能满足DSP控制器高速高性能以及稳定性的要求,建立了基于增量式数字PID控制的全闭环控制系统,从而利用对电动机的转动速度的控制来实现DSP数控系统的高性能和稳定性控制的要求,并通过仿真比较了普通PID控制与TMS320LF2407A DSP的增量式PID控制,结果表明该控制方案具有可行性和有效性,并且在很大程度上提高了系统的实时控制和稳定控制,并且对于DSP数控系统在工程应用上的深入研究提供了一定的参考价值.Depending on the situation that the traditional PID control method can not satisfy the high perform- ance and stability of the DSP controller in the continuous control process, an embedded NC motion system based on the upper and lower computer of ＂PC ＋ DSP controller＂ is proposed. Mainly by adjusting the motor rotation speed to achieve the aim of high performance and stability of DSP NC system, and by comparing common PID controller with the incremental digital PID controller on the basis of TMS320LF2407A DSP, the closed loop control system based on the incremental digital PID controller is established, and the feasibility and validity of the control scheme in this paper is testified by. the simulation results, which largely optimizes the system capability of real-time control and stability control, and also provides a certain reference value for further study of DSP NC system fin engineering application.
