Abstract EN
The direct-fired system with duplex inlet and outlet ball mill has strong hysteresis and nonlinearity.
The original control system is difficult to meet the requirements.
Model predictive control (MPC) method is designed for delay problems, but, as the most commonly used rolling optimization method, particle swarm optimization (PSO) has the defects of easy to fall into local minimum and non-adjustable parameters.
Firstly, a LS-SVM model of mill output is established and is verified by simulation in this paper.
Then, a particle similarity function is proposed, and based on this function a parameter adaptive particle swarm optimization algorithm (HPAPSO) is proposed.
In this new method, the weights and acceleration coefficients of PSO are dynamically adjusted.
It is verified by two common test functions through Matlab software that its convergence speed is faster and convergence accuracy is higher than standard PSO.
Finally, this new optimization algorithm is combined with MPC for solving control problem of mill system.
The MPC based on HPAPSO (HPAPSO-MPC) algorithms is compared with MPC based on PAPSO (PAPSO-MPC) and PID control method through simulation experiments.
The results show that HPAPSO-MPC method is more accurate and can achieve better regulation performance than PAPSO-MPC and PID method.
