Abstract :
The problem of offset elimination in adaptive control systems is considered. The key idea is to constrain the estimator in order to ensure that the DC gain of the feedforward reference model and the feedback polynomial of the adaptive controller are always equal, thus allowing the loop integrator to work properly
