数字随动系统的设计和仿真

为满足跟踪系统高速度、高加速度及高精度的要求，在模拟控制系统的基础上，用数字算法代替模拟系统中的位置回路校正电路、速度回路校正电路、脉冲调宽电路，构成数字随动系统，这样它可以有效地采用多种控制算法，实现系统的性能指标，并且系统调试方便，对外的接口少，可靠性高。

Design and Simulation of Digital Tracking System

In order to fulfilling the requirements of high-speed, high acceleration and highprecision in the tracking system, on the basis of simulation for control system, theposition loop correction circuit, speed loop correction circuit and pulse width modulationcircuit in analog system are replaced with digital algorithm and a digital tracking systemis formed. In this way it can effectively apply many control algorithms and the technicalspecifications can be performed, thus the system will have advantages of convenientadjustment, less external interface and high reliability.
