Study on 2DF PID controller in the application of constant pressure water supply
Abstract:In this paper, based on 2DF PID control, in a dynamic analysis way we establish hydraulic control model of the object. Operating frequency and converted frequency converter increases hybrid control of two induction motors (ie one for two), constitute the energy-pressure water supply system. Configuration parameters of the model and simulation testing, comparison and analysis of transient response. To prove that two degrees of freedom PID controller is better, has better real-time and stability.This article will focus on two degrees of freedom PID in Water Supply in the application.
Keywords: PID control two freedom degree Constant pressure water supply
