Application of improved particle swarm algorithm in optimization design of agricultural engineering

Improved particle swarm algorithms are used in two rural practical optimization examples. Models of rural pump house steel structure and rural electrical station var compensator are developed. Simulation with MATLAB program are made in the two models. The simulation results show that the optimized pump house steel structure weighs 27.37% than original one does and minimum costs of electrical station var compensator are realized. The algorithms are practical in agricultural engineering and provide new ways for solving similar complicated agricultural engineering optimization problems.
