摘要：In this paper the elevation and traveling control strategy-fuzzy logic which is based on the LQR for a helicopter with three degrees of freedom is considered. The characteristic of channel coupling and nonlinearity of the system will be resolved by dividing the workplace into 4 phases which the system has a linear behavior, the phases are independently considered and LQR controllers are designed separately. It is then shown that fuzzy logic is used to combine all phases and chooses the appropriate controller parameters for the appropriate phase and so on can stabilize the whole nonlinear system The performance of this strategy is shown by real response in the end of the paper compared to simple LQR. ? 2010 IEEE.
