Integrator windupIntegrator windup is illustrated in the figure below, which shows simulation of a system where the process dynamics is a saturation at a level of ±0.1 followed by a linear system with the transfer function:Because of the saturation in the actuator, the control signal saturates...
The main element of the controller is a fixed-gain proportional control; the addition of a modified tracking anti-windup integrator is first examined and... AA Khayyat,B Heinrichs,N Sepehri - 《Mechatronics》 被引量: 19发表: 1996年 Anti-windup proportional plus integral controller A proportion...
This paper is concerned with the design of dynamic anti-integrator-windup controllers for critically stable linear systems. The constant gain for anti-windup in the conventional approach is extended to a transfer function. It is also shown that the proposed compensator design is an extension of ...

This paper describes the development of an anti-windup scheme for systems which consist of a parallel set of double integrators preceded by a static coupling element and a saturation nonlinearity. A class of anti-windup compensators are proposed which can guarantee global asymptotic stability of the...

This example is a control system, where the plant is represented by an integrator with a 5 s output delay and the controller has a modified Smith predictor structure, as represented in Fig. 4. Notice that since the state matrix of the plant is not Hurwitz, the anti-windup approach of [...
