Popis:	This paper describes a new gain scheduling algorithm for handeling the problem of hard nonlinearities like input rate and magnitude saturations. The proposed algorithm was originally designed for stabilization of integrator chains with input rate saturation. Here it is shown that the gain scheduler also is effective for rudder roll control systems. The approach is to reduce the controller gains of a linear controller on-line in an computational effective way. A simulation study comparing the algorithm with the Automatic Gain Controller (AGC) of Van der Klugt (1987) is included.
