Background. Integrator windup is a problem in PID feedback controllers that results in overshoot that would not occur if … 2003-02-01 for alternative anti windup and modified anti windup; b and r are chosen to be 1, as suggested. The anti windup strategies were applied to all PID structures except the Series PID. The structure of Series PID does not require anti windup, as this PID form can be implemented to counter actuator saturation. The three different anti windup structures control loop employs a PI, PID and anti-windup PI controller for the speed control of the PMDC motor. A comparative study is made between conventional PI, PID and the anti-windup PI controllers. The system is simulated using Matlab/Simulink and the properties of these controllers were measured and tabulated. The Discrete PI Controller block implements discrete PI control with external anti-windup input.

Simulink is offering two options: back calculation and clamping (documentation) which seem to deliver equal results. I know what back calculation is doing mathematically.

In this notebook we are going to review a simple implementation of anti-windup system for a PID controller based on the classical implementation from (Åstrom,Hägglund, 2005). For better understand the problem of anti-windup, it is useful to implement a regular first order model.

简述五种PID积分抗饱和（ANTI-Windup）方法 PID控制是应用最广泛的控制结构，但是如果仅仅使用最简单的PID，大概率是不合格的。 PID控制中积分项的作用是抵抗常值‘’力‘’的干扰，保证系统的稳态精度，但是积分项很容易陷入饱和，导致系统超调与迟钝（注1），下面简述几种积分抗饱和的方法。 Anti-windup is a method of counteracting the windup that happens in the integration that occurs in the integral controller of the PID. Back-Calculation and Tracking When the output is saturated, the integral term in the controller is recomputed so that it too is at the saturation limit.

Viewed 759 times 3. 1 \$\begingroup\$ I'm implementing a PID controller in software. Using P+D only doesn't bring me close enough to my set-point so I decided to also use an Integrator with Anti-Windup.
