In particular, the choice of filter to make the controller proper, the use of a feedforward action and the selection of an anti-windup strategy are addressed.

6 2E1252 Control Theory and Practice Mikael Johansson mikaelj@ee.kth.se Summary The problem with limited actuation: • New phenomena, not predicted by linear control theory – controller, plant states “wind up Lecture: Anti-windup techniques Anti-windup schemes: Ad hoc methods Anti-windup #3: Conditional integration The PID control law is u(t)=Kp(br(t) y(t))+I(t) KpTd dy(t) dt =Kpbr(t) Kpyp(t)+I(t) where yp(t)=y(t)+Td dy(t) dt is the prediction of the output for time t+Td Consider the proportional band [yl(t),yh(t)]for yp(t)in which the corresponding u is not saturating I need to implement an anti-windup (output limitation) for my PID controller. Simulink is offering two options: back calculation and clamping (documentation) which seem to deliver equal results.I know what back calculation is doing mathematically. An anti-windup scheme for proportional-integral-derivative controllers is presented. The approach is based on the combined use of back-calculation and conditional integration anti-windup techniques. In this way, the disadvantages that can hinder previously proposed strategies are overcome. Specifically, the method can guarantee a satisfactory performance for processes with different normalised Anti-windup systems. 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. In this case we consider the system: This paper presents how to eliminate the undesired effect occurred in the PI or PID controller called integrator-windup by using four different methods. These different methods are known as anti-windup strategies. A Simulink-Matlab program has been used to investigate the results and the performance of the four anti-windup strategies. The controller, actuator, saturation and planet transfer Show plots to illustrate the windup that are similar to the ones in the handout (i.e., as in Fig. 2.4 there). • Integrator Windup Scheme Design: Next, design an anti-windup scheme (like in Fig. 2.5B in the handout on PID control) that will mitigate the integral windup effect (as in Fig. 2.6 in the handout; see also Fig. 2.7).
