Abstract:

To improve the diagnosability of unmanned aerial vehicles (UAVs), this paper proposes an optimal design strategy for diagnosability based on structural redundant sensor configurations and the grey wolf optimization algorithm. Firstly, to make up for the defect of structural analysis in measuring the difficulty of fault diagnosis, a quantitative evaluation method of diagnosability based on Wasserstein distance is proposed. Secondly, a structural redundant sensor configuration algorithm is designed to maximize the system's diagnosability with the lowest sensor configuration cost. Finally, a diagnosability optimization design strategy based on the gray wolf optimization algorithm is proposed to minimize the design cost of the diagnosability system while meeting the qualitative and quantitative diagnosability requirements. Based on the fixed UAV structural model, using the proposed algorithm, the system detectability and isolation rate reaches 100% with the minimum cost of optimal sensor configuration. The optimization strategy based on qualitative evaluation makes the diagnostic cost shrink by 83%, which is a saving of 2% to 15% compared with the other algorithms. The optimization strategy based on quantitative evaluation makes the diagnostic cost shrink by 90%, which is a saving of 0% to 25% compared with the other algorithms.
