摘要
针对DMC算法无法直接对非自衡对象进行控制的特点 ,推导出了一种基于非自衡对象阶跃响应的改进动态矩阵控制算法。该算法对DMC预测模型的误差 ,采用实际输出的变化趋势校正。仿真结果表明 ,所提出的算法对于设定值有良好的跟踪特性 ,具有很强的抗干扰能力和快速调节性能 。
A improved dynamic matrix control algorithm for a non-self-regulating plant is presented based on step response.The algorthm uses practical output's transformation tendency to adjust DMC predictive model's errors.Simulation results show that the algorithm has highly rejection and quickly adjust characteristic and verify that the algorithm's availability for non-self-regulation plant.
