Abstract :
We consider the problem of anti-windup compensation based on coprime factorizations, for asymptotically stable plants with an input saturation nonlinearity. Firstly, we state a stability criterion for the nonlinear system which guarantees finite-gain L2 stability. Then we propose an H∞-based synthesis method which is guaranteed a priori to stabilize the system with a guaranteed level of L2 performance
