【摘要】 一种以ＭＣＳ—５１系列单片机为核心的直流电机光电锁相速度控制系统。该系统的特点是采用光电编码器作为速度传感器，将传统的ＰＩＤ数字控制甚至控制用于ＤＣＣ控制之中，由单片机完成ＣＤＣ的控制。给出了速度控制系统的软硬件设计，参量分析及结论更多还原

【Abstract】 A MCS 51 single chip micrdcomputer based phase locked speed contool system of DC motor is develuped.The characteristic of the system is the employment of an optical electronic encoder an the speed sensor.Conventional proportional integral-derivative(PID)digital control laws or even a modern control algorithm have been applied in digital computer-control(DCC).A microcomputer with limited computing capabilities and memory is used to complete computer direct control(CDC).The hardware and software desgin,parameter analyses and the conclusion of the speed control system are given in detail.更多还原
