Abstract [en]

When several control signals share the same physical actuators, actuator saturation has the effect of giving coupling between control loops which are otherwise decoupled. This effect occurs e.g. in aircraft control where the elevator and aileron functions often use the same physical control surfaces. The effect is particularly important when one of the loops is open loop unstable. The paper consider the effects on the stabilizable region of cross coupling with another control loop. To give further insight simple optimal control problems are considered.
