跟踪程序

For example, the motion need to be divided into some short motion segments when the trajectory change rapidly、the executing system ought to have great instantaneity, direction changing, and the program need to avoid the methods that hold some time to calculate ,or the method has low priority level.

在轨迹变动较大的地方需要将运动段细分再进行跟踪；执行机构必须具备较强的即时性、较好的换向性能；程序编制需要避开优先级别低，计算占用时间长的方法等。

This invention relates to a DC linear motor digital controller including a central processor circuit, a data memory, a program memory, an A/D conversion circuit, a D/A conversion circuit, a linear shift orthogonal code pulse signal circuit, a signal isolation circuit, among which, the center processor circuit is composed of a special DSP chip controlled by the motor, a complicated programmable logic device CPLD combining with a peripheral expanding circuit, said digital controller fully utilizes the motor to control the special DSP chip to integral DSP kernel CZXLP and the rich external circuit in a single chip to make up of a digital controller for controlling high frequency response DC linear motor with small volume, low dissipation and high reliability.
