Description

It is an acknowledged fact in the field of engineering that autonomous helicopters are realizable. This is evident as many researches in the matured area of autonomous helicopters have reported the success of autonomous flight [1], [2], [3]. Numerous types of control algorithms have been applied successfully to enable satisfactory autonomous flight performance such as Model Reference Adaptive Control with Artificial Neural Networks [2], [4], Model Predictive Control [3], Linear Quadratic with Integral Control [5], Fuzzy tuned PI Control [6] and a spectrum of other classical and modern control techniques. However, all these reports either did not point out the robustness of their systems against external disturbances, or assumed that they could handle the unmeasured disturbances to a certain extent. To be precise, there has been no apparent research in autonomous helicopters addressing the capability of the helicopters performing satisfactory flight in harsh weather conditions. To effectively solve this problem, one of the methods would involve modelling the dynamics of the wind disturbances (weather condition to be considered) and applying a feed forward controller to suppress the effects of the measured disturbances (wind).
