Abstract

Optimal sensor placement is foundation and guarantee for design of (Prognostics and Health Management

PHM)system for avionics.The fault-sensor dependency matrix is improved which considers the failure probability of the sensors firstly.Based on this

the constraint optimization model is established and the improved discrete PSO algorithm is used to solve the problem.The algorithm designs the fitness function by the characteristics of optimal sensor placement

and the inertia weight is adjusted adaptively based on the swarm's premature degree which can avoid algorithm limits to local extremum and accelerate the convergence speed.The simulation examples demonstrate that the proposed method is effective

and the optimization results meet all the testability index requirements of system

and it can provide effective direction to the optimal sensor placement of PHM system for avionics.
