摘要
针对非线性预测控制系统中需要实时求解非线性规划问题,基于差异演化算法(DE)提出了一种非线性预测控制的新方法。差异演化算法是进化算法的一种,具有全局最优、稳健性强、收敛速度快、及参数调整简单等优点,用于求解非线性预测控制问题中的非线性规划问题具有明显优势。该算法应用于化工过程和化学反应的pH值控制仿真中,仿真结果说明了该方法的有效性。
To the problem that the nonlinear programming is needed in nonlinear predictive control systems, a method is proposed for the non-linear model predictive control based on the differential evolution （DE）algorithm, The DE algorithm is one kind of the evolutionary algorithms, which has many advantages such as global optimum, robust, fast convergence and few parameters to handle. So it will be effective to be used in the nonlinear predictive control systems, The proposed method is applied to the pH neutralization system, and simulation results show its efficiency.
