Helicopter Cable-Orientation Adaptive Fuzzy Control System Design Based on Ant Colony Optimization
Abstract:
Aiming at the complexity of helicopter cable-orientation and high accuracy requirements, a variable universe fuzzy controller combined with ant colony optimization (ACO) is proposed. The ACO is studied and improved to be used in continuous domain. The solution space is decomposed into finite grids then the ACO can be used to optimize the contraction and expansion factors of the universes. The reference cable angle is calculated and the helicopter cable-orientation control system is designed. The adaptive fuzzy controller with variable universe based on ACO is adopted to keep the ground velocity of helicopter at zero. Simulation results indicate that the controller designed in this paper has a better performance than common variable universe fuzzy controller.
