English Description：
Particle swarm optimization, also known as particle swarm optimization or particle swarm optimization, is abbreviated as PSO. It has the advantages of high precision and fast convergence, and is widely used in system identification, function optimization and other fields. PSO. M is the identification program of particle swarm optimization algorithm. On this basis, we need to write the objective function calculation program to realize the parameter identification of different systems< br/>(Particle swarm optimization (PSO), also known as particle swarm optimization algorithm or
