Now I am showing anti-windup via the two sets of back-to-back zeners: One for the integrator and one for the final summation. Also shown is a reset for the integrator. Now let's say I never want to command my motor to go > 80rpm, be it due to some safety concern or other considerations.

Hi,A supplier has advised that anti-windup will be required for their equipment.They have found for successful implementation (using other PLCs) they need to feed back Y-output to loop, otherwise will have PID windup problems.This is not something I have Sliding Mode Anti-windup Strategy for Mass Flow-Rate Regulation of Compressors with Rate-Limited Motors Yousif Eldigair, Cristian Kunusch, Carlos Ocampo-Martinez, Pablo Camocardi Abstract—In this paper, the control of the mass flow-rate for a centrifugal compressor is discussed. The compressor is driven by a rate-limited actuating motor.

• Maintain the integral errors “small.” November 21, 2010 In this case, anti-windup can actually involve the integrator being turned off for periods of time until the response falls back into an acceptable range. This usually occurs when the controller's output can no longer affect the controlled variable, or if the controller is part of a selection scheme and it is selected right. Back calculation anti-windup scheme can be viewed as supplying a supplementary feedback path around the integrator. This feedback becomes active and helps stabilize the integrator only when the main feedback loop is open due to saturation. To experiment with this scheme, use an Xcos model awupid_m2.zcos in Figure 5. Anti-windup circuitry is one way to achieve this. Configuring the Block for Anti-Windup Based on Back-Calculation.

To eliminate this integral accumulation beyond saturation limits of final control element the anti-windup technique should be used in design of controller.

Fig. 7: Tracking anti-windup, back-calculation (equivalent to Scheme 5) [4][1] Fig. 8: Modified tracking anti-windup (introduction of an additional limit on the proportional part of the control To prevent excessive overshoot, the block can use back calculation to implement an external anti-windup mechanism. It inputs du(k), the difference between the saturated control signal, u sat (k), and the calculated unsaturated control signal, u(k). It then multiplies the difference by the anti-windup coefficient and adds the amplified signal Posts: 1529.

Find a value of β that will result in integrator windup. 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 3. It extends the control loop by incorporating a static anti-windup mechanism in order to overcome a potential performance degradation caused by actuator saturation (Corollary 3).

Therefore an actuator model can be used inside the controller to yield this difference.

Set T in = 40 degrees C, and let the control system settle to a steady state. Then reduce T in to 10 degrees C and keep T in at this value for about 100min. Does the control variable go into saturation? Then increase T in back to 40 degrees. We try to explain the philosophy pursued by the anti-windup compensation together with a bit of history allowing us to show the development of the various techniques.
