1.引言由于在电子设计和控制应用中使用了微处理器,增加了灵活性并使价格降低,故其应用日益骤增。系统中的一些控制和逻辑功能由微处理器来完成的增量运动伺服系统,就是其应用之一。虽然这样的系统目前还不普遍,但可预料,不久的将来多数增量运动伺服系统都会采用微处理器作为控制器。 1. Introduction Due to the increased use of microprocessors in electronic design and control applications, which increases flexibility and lowers prices, their applications are rapidly increasing. Some of the system’s control and logic functions by the microprocessor to complete the incremental motion servo system, is one of its applications. Although such a system is not yet widespread, it is expected that most incremental motion servo systems will use microprocessors as controllers in the near future.
