Abstract | The invention discloses a parameter estimation method and device for a catalytic cracking kinetic model, and belongs to the technical field of petrochemical engineering. The parameter estimation method comprises the step of solving a catalytic cracking kinetic model by adopting a particle swarm algorithm until the fitness reaches a termination condition. Particle swarms in the particle swarm algorithm comprise sub-particle swarms used for being concentrated in a partial region of a search interval and main particle swarms used for being dispersed in the whole search interval. The termination condition of the fitness is that the obtained solution is an optimal solution or continuous solving is impossible. According to the method, two particle swarms with clear division of labor are used, the sub-particle swarms are beneficial to quickly finding the local optimal point and accelerating the convergence rate of the algorithm, and meanwhile, the main particle swarms are dispersed in the whole search interval, so t |
