Design of Self Tuning of Current Loop Parameter PI Controller

Abstract

PID control is one of the earliest developed control strategies. Because of its simple algorithm, good robustness and high reliability, it is widely used in industrial process control. Up to now, about 90% of the control loops have the PID structure. The actual industrial production process is often nonlinear and uncertain, and it is difficult to establish an accurate mathematical model. The dynamic decoupling control and anti-saturation design in this paper are all related to the PI controller of the current loop.
