New Paper: Designing & Optimization of the Controller Parameters for CSTR System using Particle Swarm Optimization

Vishal Vishnoi (Department of Electrical Engineering, Gujrat Technological University) discusses designing and optimization of the controller parameters for continuous stirred tank reactor systems using particle swarm optimization. The paper can be downloaded here. The author mentions the sequential parameter optimization in the following context:

[PSO] … is motivated by the observation of social interaction and animal behaviors such as fish schooling and bird flocking. It mimics the way they find food by the cooperation and competition among the entire population [15]. A swarm consists of individuals, called particles, each of which represents a different possible set of the unknown parameters to be optimized. The swarm is initialized with a population of random solutions [16].
The goal is to efficiently search the solution space by swarming the particles towards the best fitting solution encountered in previous iterations with the intention of encountering better solutions through the course of the process and eventually converging on a single minimum or maximum solution [17].
