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

Algorithm 1

The standard PF algorithm.
 A particle is produced by a priori probability , and the total weight of all particles is , making .
 Prediction: Use equation of State (1) 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 is obtained as . The priori condition probability density of system states is chosen as the important density function .
 Resampling: A new set of particles is obtained.
End For
