Particle Swarm Optimizer with Integral Controller
Jianchao Zeng, Zhihua Cui · 2006
TRhe evoluionary equations of PSO are secondorder discree ime hear stochastic system. It can be regarded as a control plant, and Intreducing a controller to regulate the dynamic evolutionary behaviors of PSO. In the paper, z-transformation is used to evolutionary equations, and the system structure diagram is obtained. Then, an Inetegral controller is introduced to PSO to give an Integral-PSO algorithm. Meanwhile, the integral-PSO is analyzed through the support set of sample space of particles and linear system theory for the convergence condtitions and diversity of particles., Finally, the simulation results for the test functions are given to show that the integral-PSO is more efficiency than the original PSO.
