摘要

Most, if not all, flight control systems are subject to saturation nonlinearities such as amplitude limiting. These are often referred to as "nuisance" nonlinearities, existing as they do in almost all designs. However, when such saturations do occur, flight control system performance can be degraded considerably. A technique is presented which can allow the performance of a multi-input, multi-output control system design with stable plant to be improved when operating in the presence of saturating nonlinearities. The technique is an extension of that previously discussed in the literature with regard to single-input, single output systems. An example of the design technique is presented dealing with a longitudinal autopilot design of a simple rotorcraft model, wherein command limiting in the airspeed and altitude command modes is encountered.
