ZHU Xi-hua, LI Ying-hui, LI Ning, et al. Optimal Sensor Placement Design Based on Improved Discrete PSO Algorithm[J]. Acta Electronica Sinica, 2013, 41(10): 2104-2108.
Optimal sensor placement is important content of testability design for complicated systems
which belongs to the typical combinatorial optimization problem.Based on the improvement of the fault-sensor correlation matrix
the constraint optimization model is set up which considers the fault detection abilities of the sensors.The ergodic of chaos has been used to initialize the parameters of the particles
and the inertia weight is adjusted adaptively according to the swarm's premature convergence degree.Besides
the update of the particle's position has been redefined
then the improved discrete PSO algorithm is used to solve the optimization model.The simulation examples demonstrate that the proposed method is effective
and the optimization results can satisfy all the requests of the system
and it is a feasible approach for optimal sensor placement for complicated systems.
