Design of PID controller based on PSO algorithm and FPGA

An innovative design method of PID controller based on particle swarm optimization (PSO) algorithm and FPGA is introduced. At first, with the Simulink of MATLAB, the optimized parameters of PID controller are obtained based on PSO in the closed-loop control system. Then under FPGA's controller based on FPGA and PSO algorithm is verified, and it has some advantages such as design flexible, self-tuning on line, high reliability, short cycle of technical development, high running speed and so on. This intelligent PID controller based on FPGA and PSO algorithm can be applied in high control precision digital control system with high speed responsibility and high stability.
