Anti windup basically controls the integrator component accumulation in the autopilot design Proportional Integral Controller: Discretization, Integrator Windup, and Anti-windup. This video discussed the discretization of integrator, the problems ass 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. Integrator anti-windup can be used to avoid this overshoot. Several anti-windup techniques exist; two common ones are back-calculation and clamping. Back-Calculation Back-calculation uses the difference between the unsaturated and saturated controller output as feedback that unwinds the integral accumulator.

It can also be observed from the simulation results that performance of fuzzy controller is better during the case of speed variation.

An illustrative example as well as a case study based on a one-machine inﬁnite-busnetwork show how the proposed approach works and discusses the effects of the Use anti-windup schemes to prevent integration wind-up in PID controllers when the actuators are saturated. We use the PID Controller block in Simulink® which features two built-in anti-windup methods, back-calculation and clamping, as well as a tracking mode to handle more complex scenarios. The Discrete PI Controller with Integral Anti-Windup block implements discrete PI control with internal anti-windup. The integral component of the PI controller which adds the reset rate will accumulates according specified time cycles.

The DC Current Controller block implements a discrete-time proportional-integral (PI) DC voltage controller. The signal block provides a PID(T1)-controller with Anti-Reset-Windup and bump-reduction. The PT1-part of the PIDT1-block can be switched off and the integrator of the PIDT1-controller is resetable.

This paper proposes a new type of anti-windup PI controller, SIPIC for motor position control application and aims to validate the performance of this controller as compared to conventional PI controller. Integral windup, also known as integrator windup or reset windup, refers to the situation in a PID feedback controller where a large change in setpoint occurs (say a positive change) and the integral term accumulates a significant error during the rise (windup), thus overshooting and continuing to increase as this accumulated error is unwound (offset by errors in the other direction).
