The Nonlinear Predictive Control of Die Casting Machine for Multivariable Injection Process
摘要
Abstract
In the electric hydraulic servo control system during injection process of die casting machine,this paper presents a nonlinear-predictive-control method of die casting machine for multivariable injection process based on adaptive differential chaotic evolutional algorithm.The tent map is embedded into the adaptive differential evolution algorithm (DE),which has improved the generating process of DE algorithm for the crossover factor and compiling factor.The results of simulation experiment show that by using the intelligent algorithm to optimize injection parameters of die-casting PID controller,we can achieve fast optimization of die-casting machine injection speed and make the dynamic characteristics of nonlinear predictive control better,and the control precision more higher,so as to achieve the optimal-control purpose for the system.关键词
