摘要
电动调节阀的输出很难用一个准确的数学模型来描述,但可以准确地测量。针对这一特点,步进式控制不直接对输入信号进行响应,而是分若干个固定的步长,根据每次的测量结果使输入指令信号一步一步地逼近设定量。通过合理的控制参数设置,该方法使控制对象运行平稳,适用于对响应速度要求不高的流量或压力的跟随或稳定控制。
It is difficult to describe the output of an electric regulating valve with an accurate mathematical model, but it can be accurately measured. With that in mind step-by-step control does not directly respond to the input signal, but a number of fixed points of each step in accordance with the measurement results of the output signal to guide instruction input signal step by step approach to setting volume. The adoption of a reasonable set of control parameters, this method will enable the controlling target running smoothly. This method is suitable for follow controls or stability controls of flow or pressure less demanding in response to the speed.
