As fixed-parameter control can not satisfy control requirements when helicopter is aviating in large scale flight envelop, this paper proposes a new control law design to adjust parameters on-line. Firstly a parameter-mapping approach is developed to design flight control parameters at certain flight conditions according to the desired system performance.(More)
Based on T-S model, a method is developed for designing output feedback sliding mode controller. As the state variables are immeasurable in practice, iterative linear matrix inequality (ILMI) is applied to build sliding manifold only with output information. According to the requirements of system performance, the parameter robust design method is adopted(More)
