摘要
针对多变量有约束动态矩阵控制问题 ,以输出预测值与未来参考轨迹序列误差的绝对值之和作为性能指标 ,通过线性化处理使其转化为目的规划问题 ,从而使在线滚动优化变得非常容易 ,并可充分利用全部操作变量优化系统的动态性能。当约束遭到扰动短暂破坏时 ,不会象线性规划那样终止计算 ,而是继续向参考轨迹逼近 ,在有限时域内达到设定值。仿真实例验证了该算法的有效性。
Focusing on the constrained multivariable dynamic matrix control, the sum of the absolute error values between predictive outputs and reference trajectory sequences is taken as the criterion function. By linearization of the criterion function, the on-line optimization is cast as goal programming which can be easily solved. The presented algorithm can make full use of all manipulative variables to optimize the dynamic performance of process. Unlike linear programming, when constraints are not satisfied due to temporary disturbance, it continues to approach reference trajectory and reach the set-point in finite horizon. A simulation example shows the effective performance of the algorithm.
