Biogeography Optimization Algorithm for DC Motor PID Control

Biogeography optimization algorithm BBO is a new optimization algorithm based on biogeography. Unique migration pattern of BBO makes good habitat feature information can be widely distributed among multiple habitats, showing a diversity of solutions. It is applied to the DC motor PID control problems and compared with genetic algorithms GA, differential evolution DE, particle swarm optimization PSO. Experimental results show that BBO has the ability of searching optimal solution in a small local neighborhood space. The output of PID control system of DC motor optimized under BBO has no overshoot, no steady-state error and has the shortest system dynamic response time.
