摘要

A control system design technique based upon pseudosliding mode control is applied to the design of a flight control system for a linear model of a UH-60A rotorcraft near hover. The vehicle model contains 28 states and includes rotor degrees of freedom. The proposed technique interprets the pseudosliding mode design in the frequency domain. Rotor and actuator dynamics are treated as parasitic elements in the design procedure. The robustness of the design is evaluated in a computer simulation of the vehicle in which significant changes in the characteristics of the nominal vehicle, control system, and sensors are introduced. The role of high-performance actuators in the design implementation is emphasized.
