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.

First, we propose the structure of an output feedback model predictive controller with an anti‐windup compensator. • Illustrate Anti-Windup Effect: Use a step input for θ d with a magnitude of β rad. Find a value of β that will result in integrator windup.

Anti-windup schemes are based on the difference between actuator input (controller output) and actuator output. These signals are not always available. Therefore an actuator model can be used inside the controller to yield this difference. In the library models,

The linear range of a control system can be limited by saturation of the feedback controller output. Anti-windup circuitry is one way to achieve this. Configuring the Block for Anti-Windup Based on Back-Calculation. The back-calculation anti-windup method uses a feedback loop to discharge the PID Controller internal integrator when the controller hits specified saturation limits and enters nonlinear operation.

The PT1-part of the PIDT1-block can be switched off and the … Se hela listan på mathworks.com Integrator anti-windup can be used to avoid this overshoot. Several anti-windup techniques exist; two common ones are back-calculation and clamping.
