Application of the Artificial Fish School Algorithm and Particle Filter Algorithm in the Industrial Process Control Particle Filtering Algorithm for Industrial Process Control

Algorithm 2

The SOSS-based PF algorithm.
 A particle set , is initialized, and a particle is produced by a priori probability , with , and all particles have a weight of , .
 Prediction: Use equation of state to predict the unknown state
 Calculate particle weights:
End For
 Normalized weight,
End For
 Then, the minimum mean square estimate of the state vector at time k is obtained as . The priori condition probability density of system states is chosen as the important density function .
End For
