摘要
作为直线电机伺服控制系统的一个环节,位置检测是直线电机伺服控制的关键技术之一。在分析光栅信号检测及其输出信号的基础上,解决了使用DSP对光栅信号进行接收和处理的问题,提出了对其采样时的周期选择方法,同时,在PID算法的基础上制定了电机的控制方案,用以实现直线电机的高响应。
As a loop in the servo control system of the linear motor,the positional detection is one of key technologys for positional servo control of it.On the basis of the analysis of the detection of the signals form the linear encoder and the signals itself,the paper finds a solution to the receiving and disposal of the signals,and finds a way to select a sampling period when sampling the signals.At the same time,the scheme used to control the motor is determined based on PID arithmetic,through which the control of the motor with high response and high precision can be realized.
